We evaluated the effects of an instructional package on the emergence of novel intraverbals in children diagnosed with autism. Participants were two boys with a diagnosis of autism who had tact and listener repertoires for common objects and events, some intraverbal responses, and showed an ability to learn new intraverbal responses through direct instruction prior to participating in the study. Tact training, listener training, sorting training, and mixed training (listener and tact training) were conducted with each participant, with a probe to test for emergent intraverbals following each training step. If some emergence was seen during a probe following a training step, probes were conducted with the remaining sets to test for emergence in those sets as well. Multiple-exemplar training was conducted following the training steps if all targets within a set did not meet the criterion for emergence during probes. Results showed that for one participant, all four training steps, in addition to multiple-exemplar training, were needed to see emergence in all targets during probes for two sets, with the last two sets requiring only tact training before all targets had emerged during probes. The second participant required only tact training during three sets, with listener training required for one target in one set before all targets in all sets emerged during probes.

A follow-up was done to Leak and Fish's (1989) study of intrinsically and extrinsically religious individuals using Paulhus' (1984) Balanced Inventory of Desirable Responding, a two factor scale of socially desirable responding measuring self-deceptive enhancement (SDE) and impression management (IM). 275 introduction to psychology students were group tested and categorized by gender and by religious orientation with Allport and Ross's (1967) fourfold Religious Orientation Scale (ROS). Differences between the four types were hypothesized on the religious relevance of the SDE and IM scale items. A difference score was also computed by contrasting two instructional sets on the BIDR as a measure of variation across situations. Measures of private and public self-consciousness, social anxiety, fear of negative evaluation, and self esteem were included.

Traditional two-process theory predicts that a conditioned stimulus (CS) paired with shock offset on Pavlovian trials will inhibit operant avoidance responding. Two explanations of the inhibitory mechanism involved were compared: contemporaneous pairing of CS with a hedonic relief reaction versus the predictive, discriminative relationship of CS to the non-shock interval. The pattern of avoidance inhibition associated with cessation CSs paired with electric shocks of constant duration was expected to be different from the pattern accompanying cessation CSs paired with shocks of variable duration. Mean rates of responding by the two groups were compared by analysis of covariance using baseline as the covariate. Neither CS displayed any reliably observable effects on avoidance rates. Possible procedural flaws and compatible improvements are discussed.

Cannabinoid agonists, including marijuana containing delta-9-tetrahydrocannabinol (THC), are found rewarding by humans. In addition to human self-reports and experimental studies that show marijuana is rewarding, contributions from preclinical studies also have implicated cannabinoid receptors in reward-motivated behavior. One way to assess these preclinical effects of cannabinoids is intracranial self-stimulation (ICSS), where an animal performs a response to receive electrical stimulation of a specific brain area or circuit known to be involved in reward. Drugs of abuse, such as psychomotor stimulants, facilitate responding for ICSS. While a few studies have shown facilitating effects of cannabinoids in rats, several have shown the opposite effect, and no studies so far have evaluated cannabinoids in mouse ICSS. Furthermore there are no studies evaluating specific inhibitors of endocannabinoid catabolic enzymes in ICSS in any species. In these studies we assessed the cannabinoid agonist THC, as well as the fatty acid amide hydrolase (FAAH) inhibitor, PF-3845, the monoacylglycerol lipase (MAGL) inhibitor JZL184, and the combined FAAH/MAGL inhibitor SA-57 in ICSS of the medial forebrain bundle in C57BL/6 mice. Additionally, we assessed the psychomotor stimulant cocaine as a positive control to facilitate ICSS. These studies were complimented with spontaneous locomotor activity and food-maintained operant experiments to assess the sensitivity of ICSS to cannabinoids. Additionally, brain endocannabinoid levels were measured in brain regions associated with the mesolimbic system after enzyme inhibitor treatments. THC, JZL184, and SA-57 all produced time-dependent reductions in ICSS that were mediated through CB1 receptors, as they were blocked by pre-treatment with the CB1 antagonist rimonabant, but not with the CB2 antagonist SR144528. PF-3845 also reduced ICSS, but did so independent of CB1 and CB2 receptors, and only with one dose (30.0 mg/kg) that has not been assessed previously in vivo. We showed that ICSS was more sensitive to the rate-reducing effects of cannabinoids than other measures of behavior with motor components including spontaneous locomotor activity and operant nose-poking for food, and that the reduction of ICSS produced by both JZL184 and SA-57 is accompanied by increases in 2-AG in mesolimbic brain areas. Thus, cannabinoids do not facilitate ICSS in C57BL/6 mice over a range of doses and pre-treatment times, similar to most studies with rats. These data suggest that cannabinoids may produce rewarding effects through non-mesolimbic areas of the brain.

Through examining the variables that contribute to the natural process of language and cognition, a promising path is paved for researchers to identify the variables that influence higher order skills, such as perspective taking, empathy and altruism. The current study implemented the PEAK Relational Training System Transformation Module Pre-Assessment Expressive portion (PEAK-T PA) as an objective behavior measure of relational framing complexity. Two additional self-report assessments were used with all subjects, including a multi-dimensional measure of empathy, referred to as the Interpersonal Reactivity Index (IRI) and the Valued Living Questionnaire (VLQ). A Pearson correlation analysis was conducted to examine the relationship between PEAK-T PA scores and IRI subscale scores. Additional Pearson correlation analysis was used to determine a relationship between PEAK-T scores and VLQ scores. A statistically significant relationship was determined between one of the relational frame subareas of the PEAK-T PA and the perspective taking IRI subscale scores. Results, limitations and future research areas associated with relational framing abilities are discussed.

Purpose:The purpose of this thesis has been to study, describe and analyze how luxury fashion brands have responded to fast fashion. Background:It has been stated that the life of luxury fashion brands has become more difficult since the proliferation of fast fashion brands. The Italian luxury fashion designer Giorgio Armani has said that "Fast fashion is a growing reality in our sector". Anna Wintour, the editor-in-chief of American Vogue has credited Zara for creating a ‘seasonless cycle for fashion’. Fast fashion brands such as H&M, Zara, Mango and Topshop have through interpreting catwalk trends with a speedy time-to-market been extremely successful at attracting the fashion conscious consumer. Even loyal high-end customers have started to mix their luxury fashion with fast fashion. Luxury fashion brands once dismissed the fast fashion brands as irrelevant to their high-end business, which however have started to drain away sales from the luxury fashion brands.Method:A qualitative research approach was taken to meet the purpose of collecting the relevant data. An interview was made with PR and Marketing Manager at Group 88, Robert Meeder who manages brands such as Gucci, Burberry and Bottega Veneta in Copenhagen. We also did a content analysis on articles collected that address the issue of how different luxury fashion brands have responded to fast fashion for the empirical study.Conclusion:Luxury fashion brands have responded to fast fashion by inclining towards the fast fashion model or reacting against it. Some of the reactions have been to offer lower priced lines under their own sub-brands. They have also allowed their customers to buy products during online webcasts in order to ensure early deliveries. Improvements have been made within logistics in order to speed up the time-to-market. The luxury fashion brands are also working more ‘seasonless’ than before and focusing on their heritage to portray a slower and more indulgent image to the consumer. / Program: Magisterutbildning i Fashion Management

Mindfulness meditation is a growing area of interest for both mental health professionals and the general public alike. Beneficial outcomes are associated with these practices, although the variety of measurement techniques makes research difficult to interpret. Definitions of these constructs are varied, and anecdotal accounts point to the idea that many people hold misconceptions about mindfulness and meditation, even when meanings are made clear. Still, no formal research has been published on misconceptions of mindfulness – or, if they exist, how such misinformation affects acquisition of related skills. Furthermore, mindfulness has been incorporated into therapeutic modalities without much consideration for context, including the client's learning history. The current analogue study examined how the presentation of mindfulness meditations (i.e., inaccurate rationale/meditation and accurate rationale/meditation) affects an individual's practice. Specifically, self-reported mindfulness and meditation skills, mood questionnaires, a matching-to-sample task, and qualitative measurements were used to assess acquisition. Although primary hypotheses did not yield significant findings, results from both preliminary and exploratory analyses demonstrate significant findings with regard to teaching, learning, and measurement related to mindfulness meditation. The results, future directions, and limitations are discussed.

abstract: Temporal bisection is a common procedure for the study of interval timing in humans and non-human animals, in which participants are trained to discriminate between a “short” and a “long” interval of time. Following stable and accurate discrimination, unreinforced probe intervals between the two values are tested. In temporal bisection studies, intermediate non-reinforced probe intervals are typically arithmetically- or geometrically- spaced, yielding point of subjective equality at the arithmetic and geometric mean of the trained anchor intervals. Brown et al. (2005) suggest that judgement of the length of an interval, even when not reinforced, is influenced by its subjective length in comparison to that of other intervals. This hypothesis predicts that skewing the distribution of probe intervals shifts the psychophysical function relating interval length to the probability of reporting that interval as “long.” Data from the present temporal bisection study, using rats, suggest that there may be a within-session shift in temporal bisection responding which accounts for observed shifts in the psychophysical functions, and that this may also influence how rats categorize ambiguous intervals. / Dissertation/Thesis / Masters Thesis Psychology 2019

Major depressive disorder (MDD) is a disorder defined by mood disturbance, but the deficits in emotional reactivity that accompany MDD are not yet fully characterized. Researchers have utilized the emotion-modulated startle paradigm to investigate emotional responding among depressed individuals with mixed results. Inconsistent results may be due in part to the heterogeneity of mood disorders, including variation in mood severity. The current study utilized an emotion-modulated startle procedure with 33 individuals currently experiencing a major depressive episode, 25 individuals currently experiencing a minor depressive episode (mD), and 31 healthy controls. Severity of depression, anxiety, and positive and negative mood states were ascertained on the sample. Emotion-modulated startle failed to differentiate between mood disordered individuals and healthy controls. However, results found a significant association between abnormal patterns of emotion responding and positive affect (PA), such that individuals with low PA showed exaggerated responding to unpleasant stimuli. The results suggest that PA may be an important dimension in mood disorders that underlies abnormal emotional responses.
