Introdução: O aprendizado intencional/incidental pode influenciar a memória. A persistência deste efeito avaliado ao longo do tempo foi pouco estudada até o momento. Objetivos: Avaliar a persistência da memória comparando as aprendizagens intencional e incidental. Métodos: A amostra (120 sujeitos funcionalmente independentes, com idade variando de 18 a 81 anos), foi subdividida em dois grupos (experimental - condição ‘intenção de aprender’ - e controle). Uma abordagem ecológica foi utilizada para a avaliação do aprendizado incidental. As avaliações foram realizadas dois e sete dias após a codificação. Resultados: A intenção de aprender e a aquisição incidental (a partir de experiências de vida diária) melhoraram a recuperação da memória no dia dois, mas não sete dias após a codificação. Conclusão: Estes achados sugerem que o estado motivacional (espontâneo ou induzido) que modula o sistema da atenção deve ser importante para a melhora na recuperação das informações aprendidas. / Background: The intentional/incidental learning can influence memory. The persistence of this effect assessed over time has been little studied up to date. Objectives: To evaluate the persistence of memory comparing intentional and incidental learning conditions. Method: The sample (120 functionally independent subjects, age ranging from 18 to 81 years old), was subdivided into two groups (experimental - intention to learn condition - and control). An ecological approach was applied for the incidental learning condition. The assessments were performed two and seven days after the encoding. Results: The intention to learn and the incidental acquisition (from daily life experiences) improved performance two but not seven days after the encoding. Conclusions: These findings suggest that motivational state (spontaneous or induced) which module the system of attention may be important for the improvement in the retrieval of the information learned.

Incidental catch (bycatch) in fisheries is one of the major threats to marine mammal populations worldwide. The harbour porpoise (Phocoena phocoena, Linneaus 1758) is one of the most common cetaceans in northern Europe. Previous studies have reported high bycatch numbers of harbour porpoises in gillnet fishing operations in the North Sea and Skagerrak Sea. With the aim of disentangling the driving factors behind bycatch of harbour porpoises, I looked at the relationship between occurrence of harbour porpoise bycatch and properties of fishery and porpoise density. Parameters of fishing effort, gear characteristics and operations of 951 sets of strings of cod and pollack bottom set gillnets were collected by an on-board observer programme in the Swedish Skagerrak and Kattegat Seas during 1995-1997. Porpoise density data was generated from satellite tracking locations of 116 individuals from 1997 to 2016. Generalised linear models with binomial distribution were applied to identify the relationships between the occurrence of porpoise bycatch and seven explanatory variables extracted as soak time, string length, net height, mesh size, net bagginess, water depth and porpoise density. During the observer programme, a total of 21 porpoises were bycaught during 10,174 km*h of observed fishing effort. The total bycatch was estimated to be 2.6% of the population abundance at that time, i.e. above the maximum sustainable total anthropogenic removal (1.7%). Soak time, string length and water depth were identified to be positively related to bycatch occurrence. The findings provide guidance for bycatch mitigation measures in terms of adjusting fishing operations, improving gear and establishing separate management units. Modelling can be used to predict possible spatio-temporal high-risk hot spots for harbour porpoise as well as other marine-living species to optimise future monitoring efforts.

<p>Participants claiming to be good at evoking vivid olfactory images are assumed to have better access to odor memory. It was hypothesized that this would be reflected in better odor naming and recognition task performance. Two extreme groups of participants high and low in self-reported olfactory imagery ability were exposed to familiar and unfamiliar odors in an incidental learning session. This was followed by an episodic odor recognition and odor naming task 20 minutes later. Imagery ability was unrelated to naming and recognition. This might indicate that if high imagers have a better access to odor memory, it is not due to a stronger link between language and odor memory or better incidental encoding.</p>

<p>Based on the survey of Chinese students in a Sweden university,the present study finds out that Chinese EFL learners at a low level can benefit from incidental English vocabulary acquisition through reading aided by glosses, that they prefer glosses in reading materials, and whether Chinese gloss and English gloss differ in effectiveness on incidental vocabulary learning.</p>

<p>This study aims to investigate whether incidental methods are used in learning English vocabulary by non-English students at college in China, and in teaching English vocabulary by their oral English teachers. It also finds out what kinds of incidental strategies are used. Then based on the results of the investigation, this study puts forward some pedagogical implications for teachers.</p>

Spatiotemporal heterogeneity in predator activity can generate and influence the availability of refugia to prey. In eastern forests, white-footed mice (Peromyscus leucopus) and eastern chipmunks (Tamias striatus) are abundant generalist rodents, and large-scale removal experiments have confirmed they are important predators of gypsy moth (Lymantria dispar) pupae and songbird nests and eggs. Models predict the extinction of gypsy moth populations when confronted with abundant mouse populations, but small-scale (10s of m) heterogeneity in rodent activity may allow for the persistence of moth populations. I quantified the magnitude, variability, temporal persistence, and spatial structure of white-footed mouse and eastern chipmunk activity, and evaluated the effects of small-scale (30 x 30 m "spots") rodent removal, on 3 pairs of oak-dominated plots for 3, 2-week periods in summers 2008 and 2009 at the Cary Institute of Ecosystem Studies, Millbrook, NY, USA. Small-mammal track activity (1/check) was best fit by a beta-binomial distribution, and the mean and CV ranges of mouse and chipmunk track activity were similar between years. Disattenuated correlations of mouse and chipmunk activity were similar between sampling periods, as well as between years. I found little evidence of spatial structure in rodent activity at the scales sampled (15-250 m). Mean local track activity counterintuitively increased in removal spots compared to control spots for mice in 2008 and chipmunks in 2009. Local, between-year track activity was more strongly correlated and of greater magnitude in persistent removal spots than in non-persistent removal spots for both mice and chipmunks Environmental factors like abundant alternative food sources can influence predator foraging behavior by concentrating predator space use and altering predation rates on incidental prey items. However, the spatial scale of this aggregative effect, and impact on consumption rates on incidental prey items, are not well understood. In spring 2010, I conducted live-trapping, measured local rodent track activity, and quantified consumption rates on two incidental prey items (almonds [Prunus dulcis] and maple [Acer saccharum] seeds) on 6 plots provided with 3 supplemental food treatments (control, corn, and sunflower seeds) at Touch of Nature Environmental Center, Carbondale, IL, USA. A half-normal, cosine detectability function best fit our live-trapping data in both pre- and post-experiment trapping sessions, but considerable support remained for other models. Overall mean track activity was greater in control treatments than in sunflower and corn treatments. I found a significant interaction effect of treatment and distance, and significantly increased activity in control treatments at distances of 0, 10, and 40 m. Overall mean almond and maple seed consumption was greater in control treatments than in sunflower and corn treatments, but was greater in corn than sunflower treatments and increased from period 1 to period 3 at all distances. Mean almond consumption by mouse only and mouse + unknown predator groups was greater in control treatments than in sunflower and corn treatments. Mean maple seed consumption by mouse only and mouse + unknown predator groups was greater in control treatments than in sunflower and corn treatments.
