In anticipation of a future social interaction, socially anxious individuals (SAIs) may imagine themselves appearing stupid or foolish and predict and exaggerate the probability and costs of conveying these undesirable social images both on oneself (e.g., “I will feel stupid”) and on others impressions of oneself (e.g., “Others will think I’m stupid”). However, there is a paucity of research examining the latter bias; moreover, research regarding SAIs estimates of the probability and costs of conveying a positive impression (e.g., “I will feel smart”) has typically been neglected. Thus, the a novel questionnaire was created in order to develop a more comprehensive model of SAIs estimates of probability and costs. We expected that positive and negative, self- and other-related judgments will represent four distinct, latent constructs that will be related to trait social anxiety indirectly through fears of positive and negative evaluation per the evolutionary model of social anxiety. Structural equation modeling was used to test study hypotheses. The final sample included four hounded and seventy-four college students (307 males and 167 females). Results generally supported study hypotheses. After minor theoretically justified modifications, the hypothesized model provided good fit to the data, χ2(94) = 151.78, CFI = .99, TLI = .99, RMSEA = .04. All social appraisals (or judgments) with the exception of other-negative appraisals were indirectly related to social anxiety through fears of positive and negative evaluation. Contrary to expectations, other-positive appraisals were negatively related to fear of negative evaluation and other-negative appraisals were uncorrelated with fear of positive evaluation, providing partial incremental validity of the novel questionnaire used in this study. Results provide preliminary evidence that suggests future research should extend evaluation of SAIs anticipatory social appraisals beyond negative, self-related social impact. Implications, limitations, and future directions of the research are be discussed.

The Dunning-Kruger Effect is a metacognitive phenomenon in which individuals who perform poorly on a task believe they performed well, whereas individuals who performed very well believe their performance was only average. To date, this effect has only been investigated in the context of performance on mathematical, logical, or lexical tasks, but has yet to be explored for its generalizability in episodic memory task performance. We used a novel method to elicit the Dunning-Kruger Effect via a memory test of item and source recognition confidence. Participants studied 4 lists of words and were asked to make a simple decision about the words (source memory, i.e. Is it manmade? Is it alive?). They were later tested on their episodic memory and source memory for the words using a five-point recognition confidence scale, while electroencephalography (EEG) was recorded. After the test, participants were asked to estimate the percentile in which they performed compared to other students. Participants were separated into four quartiles based on their performance accuracy. Results showed that participants in all four groups estimated the same percentile for their performance. Participants in the bottom 25th percentile overestimated their percentile the most, while participants in the top 75th percentile slightly under-estimated their percentile, exhibiting the DKE and extending its phenomenon into studies of episodic memory. Groups were then re-categorized into participants that over-estimated, correctly estimated, and under-estimated their percentile estimate. Over-estimators responded significantly faster than under-estimators when estimating themselves as in the top percentile and they responded slower when evaluating themselves as in the bottom percentile. EEG first revealed generic scalp-wide differences within-subjects for all memory judgments as compared to all self-estimates of metacognition, indicating an effective sensitivity to task differences. More specific differences in late parietal sites were evident between high percentile estimates and low percentile estimates. Between-group differences were evident between over-estimators and under-estimators when collapsing across all Dunning-Kruger responses, which revealed a larger late parietal component (LPC) associated with recollection-based processing in under-estimators compared to those of over-estimators when assessing their memory judgements. These findings suggest that over- and under-estimators use differing cognitive strategies when assessing their performance and that under-estimators use less recollection when remembering episodic items, thereby revealing that episodic memory processes are playing a contributory role in the metacognitive judgments of illusory superiority that are characterized by the Dunning-Kruger Effect.

Anxiety is of importance within the field of cognition because it is often associated with adverse effects on attention, information processing, learning and memory (Eysenck, 1992, 2007). In existing literature, it has been reported that trait anxiety hinders cognitive performance (i.e., working memory capacity WMC). However, the relationship between trait anxiety and cognitive performance might be moderated by working memory capacity (WMC). For example, Owens (2014) reported that trait anxiety was negatively correlated with cognitive performance in the low WMC group and positively correlated to cognitive performance in the high WMC group. Although, past research on the working memory system has focused on the impairments that are triggered by trait anxiety, there may be an exception to these existing findings. Recently, Moriya & Sugiura (2012, 2018) reported that high trait anxiety paradoxically enhances visual-short term memory capacity (VSTMC). In this present study, we sought to identify if WMC modulates the relationship between trait anxiety and VSTM performance. Our first hypothesis stated that there would be a positive correlation between trait anxiety and VSTM capacity. Our second hypothesis stated that the correlation between trait anxiety and VSTM capacity would be modulated by WMC. In this current study, working memory, visual-short term memory and self‐report levels of trait anxiety, were evaluated. The results of the current study did not provide strong support for neither of our hypotheses. For hypothesis 1, we were not able to replicate Moriya and Sugiura’s findings; trait anxiety did not enhance VSTM performance. For hypothesis 2, VSTM performance was not influenced by the interaction term of WMC x trait anxiety; in such WMC and trait anxiety combined were unrelated to VSTM performance. Despite this work, we are still somewhat unclear whether trait anxiety enhances VSTM performance. Although, our data did not provide definitive support for enhanced VSTMC in high trait anxious individuals it did provide three unique findings. First, our results suggest that the level of WMC does in fact modulate the relationship between trait anxiety and VSTMC. Second, only the somatic component of trait anxiety was negatively correlated to VSTM performance for LWMC individuals. Third, WMC and VSTMC were significantly associated with one another. In closing, our three core findings may provide important insights towards improving future research when assessing the relationship between trait anxiety and VSTM performance.

The purpose of this study was to investigate the effects of a 500 Hz and 3,150 Hz one-third octave band augmentation on the speech discrimination ability of listeners with cochlear hearing impairments. The results were analyzed both within the experimental group of subjects included in the present study and in comparison with data collected on a control group of normal hearing subjects reported earlier.

Mathematics education researchers have examined the relationship between visualization and mathematics for decades (e.g., Arcavi, 2003; Bishop, 1991; Duval, 1999; Fennema & Tartre, 1985; Presmeg, 1986). Studies have linked spatial visualization ability, such as measured in mental rotation tasks, directly to mathematics self-efficacy (Pajares & Kranzler, 1995; Weckbacher & Okamoto, 2014), which in turn influences mathematics achievement (Casey, Nuttall, & Pezaris, 1997). With the important role that spatial visualization plays in learning mathematics, the recent identification of congenital aphantasia (Zeman, Dewar, & Della Sala, 2015), which is the lack of mental imagery ability, has raised new questions for mathematics education researchers. This study investigated the differences in mental rotation test performance and vividness of spatial imagery between people who have aphantasia and people who do not as a first step toward examining how aphantasia may affect mathematics learning and education. Results confirmed prior aphantasia research showing that there was no significant difference in mental rotation test performance between people with aphantasia and those without aphantasia, despite people with aphantasia reporting significantly lower vividness of spatial imagery. Results also showed that there was less difference in mental rotation test performance between the genders for people with aphantasia, while gender played a significant role in mental rotation test performance for people without aphantasia. People with aphantasia also reported lower self-efficacy in the arts than people without aphantasia. Implications of these results will be discussed within the context of current research, and possible directions for future research will be offered.

Anxiety Sensitivity (AS), the belief that anxiety-related sensations may have harmful implications, can alter autonomic nervous system (ANS) function. Exercise has previously been shown to reduce AS; however, the effects of an exercise intervention on heart rate variability (HRV), a measure of ANS function, has not been evaluated in individuals with high AS. This study sought to 1) compare resting HRV in individuals with either low (LAS) or high AS (HAS) and 2) evaluate the effects of a 2-week exercise intervention on HRV and AS. Using the Anxiety Sensitivity Index (ASI-3), participants were identified as LAS (n=9; ASI-3=5.89±1.39) or HAS (n=15; ASI-3=32.87±2.49) and subsequently completed six 20-minute moderate intensity exercise sessions. HRV and psychosocial measures were obtained at baseline and following the 2-week intervention. No significant differences (p>0.05) in time or frequency domain HRV values between groups were revealed at baseline; however, when considering the HAS group alone, strong associations were observed between the ASI-3 score and HRV values in the time domain: RMSSD (r=-0.56), SDNN (r=-0.61), and pNN50 (r=-0.53). Following the intervention, changes observed in HRV and the higher and lower order (subscale) ASI-3 scores were not different between the groups; however, a medium to large effect was observed for the higher order ASI-3 and the cognitive subscale score, suggesting that our findings were likely limited by the small sample size. Further research is warranted to evaluate the relationship between HRV and AS and should seek to determine the most effective exercise interoceptive exposure for improving AS symptomology.

The Cognitive Interview (CI) has been shown in over one hundred studies to enhance eyewitness recall. However, no study has explored whether the CI improves police job performance. The current study was the first to test the practical value of the CI in a criminal investigation, testing participants’ performance on key police tasks using either a perpetrator description elicited from a CI or from a standard police interview (SI). In an earlier study, student witnesses were exposed to a simulated robbery and were then interviewed using either a CI or an SI to elicit a description of the robber (comprised of individual descriptors). In Experiment 1, a sample of student participants (N=320) completed two investigative tasks using the descriptors: (a) identifying the perpetrator from a group of ten potential suspect photographs; and (b) allocating hours among the top three potential suspects dictated by who should be the focus of the police’s time (i.e., investigative resources). Participants also subjectively assessed each descriptor’s value in terms of completing the tasks. Presentation methods to enhance the utility of the CI were also tested. Relative to the SI, the CI resulted in a near-30% increase in accurately identifying the perpetrator. Also, significantly more hours were allocated toward investigating the perpetrator using the CI as compared with the SI. Participants did not, however, subjectively value CI descriptors more than SI descriptors; and, the CI’s utility was not enhanced by the presentation methods tested. Experiment 2 sought to reproduce and generalize the CI’s effect on investigative utility by using police officers (N=71) and student participants (N=67). As in Experiment 1, the CI significantly improved investigative performance in accurately identifying the perpetrator, and in allocating resources toward investigating the perpetrator. Police and students did not significantly differ in their performance of investigative tasks or in their utility ratings of the CI descriptors. The current study was the first to find that the CI can be properly used by police in a criminal investigation. Investigating the actual perpetrator as opposed to an innocent suspect is likely to have a domino effect on subsequent phases of an investigation.

The study looked at how misperceptions of randomness (the gambler’s fallacy or the hot-hand fallacy) would show differences in self-serving-bias through different levels of perceived control. In order to investigate this relationship between misperceptions of randomness, self-serving bias, and perceived control, the study manipulated perceived control by varying who threw the coin (experimenter/participant) and by showing a skill prime to some participants. Thus, in the experiment, participants either saw a skill prime or not by random assignment. Afterwards, the participants predicted an outcome, rated the confidence of the prediction, then the participants would throw a coin for half of the trials while the experimenter would for the other trials. Due to little variability of the self-serving bias, the analysis could not test the hypothesis. However, the study found that other variable such as confidence was able to predict the misperception of randomness when the participants threw the coin.

All athletes are driven by motivation, sources or reasons to push their bodies to their limits and continue to do so regularly. There have been several studies concerning motivation in typical athletes, and many regarding social motivation in people with High Functioning Autism (HFA), however most have been limited to children, and there have been no investigations into HFA athletes’ motivation. The current study looks into the role of social dimensions in athletics, and tests how one’s gender and placement on the Empathy Questionnaire (EQ), Systemizing Questionnaire (SQ), and on the Autism Questionnaire (AQ) affect intrinsic motivation in athletics. It was predicted that athletes with HFA would demonstrate greater levels of intrinsic motivation than those with lower scores on the Systemizing and Autism Questionnaires. The second hypothesis predicted that those who are more prone to systematizing (and perhaps higher on the AQ) would be more intrinsically motivated than those who are more prone to empathizing, as social rewards may not be as important to them. To uncover the differences between intrinsic motivation due to placement on the AQ, SQ and EQ, as well as differences between sexes and coaching feedback, a combination of Linear Regression Analyses, Independent Groups T-Tests and Correlations (n=25) were used. The first hypothesis was invalid due to lack of recruitment of HFA participants, but the second was supported by the data.

Existing literature demonstrates that infants can discriminate between categories of infant-directed (ID) speech based on the speaker’s intended message – that is, infants recognize the difference between comforting and approving ID speech, and treat different utterances from within these two categories similarly. Furthermore, the literature also demonstrates that infants understand many aspects of music and can discriminate between happy and sad music. Building on these findings, the present study investigated whether exposure to happy or sad piano music would systematically affect infants’ preferences for comforting or approving ID speech. Five- to nine-month-old infants’ preferences for comforting or approving ID speech were examined as a function of whether infants were exposed to sad or happy piano music. Seventeen (10 male, 7 female) full-term, healthy infants were included in the study. It was hypothesized that relative to infants exposed to happy music, infants exposed to sad music would demonstrate a stronger desire to hear comforting ID speech. The study employed an infant controlled, preferential looking procedure to test this hypothesis. The results of the study did not statistically support the researchers’ hypotheses. Limitations of the present work and suggestions for future research are discussed.
