An Evaluation of a Brief Multiple-Stimulus Without Replacement Preference Assessment Conducted in an Electronic Pictorial Format

We compared the results of a brief electronic pictorial multiple-stimulus without replacement (EP-MSWO) preference assessment to a brief tangible MSWO preference assessment in five children with autism. Results of both assessments yielded a match between high preferred (HP) toys for four participants and low preferred toys for three participants. The overall correlation between assessments across participants was strong and statistically significant (ρ = .67, p < .01). A reinforcer assessment conducted with three participants confirmed HP toys identified in the EP-MSWO functioned as reinforcers.     

Eyewitness memory: The impact of a negative mood during encoding and/or retrieval upon recall of a non-emotive event

The police often appeal for eyewitnesses to events that were unlikely to have been emotive when observed. An eyewitness, however, may be in a negative mood whilst encoding or retrieving such events as mood can be influenced by a range of personal, social, and environmental factors. For example, bad weather can induce a negative mood. This experiment compared the impact of negative and neutral moods during encoding and/or retrieval upon eyewitness recall of a non-emotive event. A negative mood during encoding had no impact upon the number of correct details recalled (provided participants were in a neutral mood at retrieval) but a negative mood during retrieval impaired the number of correct details recalled (provided participants were in a neutral mood at encoding). A negative mood at both time points enhanced the number of correct details recalled, demonstrating a mood-dependent memory enhancement. The forensic implications of these findings are discussed.     

Perceptions of the family, delinquency, and emotional adjustment among youth

This study explored the relationships between perceived family processes (parental bonding and parental discipline styles) and adolescent emotional and behavioural adjustment among a sample of youth. Respondents were 92 (53 female, 39 male) high school students, aged 13–17 years. Significant sex differences were noted regarding levels of self-reported delinquency and parental induction style. After controlling for sex, perceptions of low care and love withdrawal were significantly related to delinquency, while low care, overprotectiveness and love withdrawal were found to be related to poor well being. Structural equation modelling was used to further assess the relationships between perceptions of family life and the outcome variables. It was concluded that adolescent perceptions of family processes form a coherent and integrated network with implications for behavioural and emotional adjustment.     

An extension of the ‘two-baskets’ theory to Native Americans

A theory that private and collective self-cognitions are stored in separate locations in memory (Trafimow, Triandis, & Goto, 1991; Trafimow, Silverman, Fan, & Law, 1997) was tested with a sample of participants (Native Americans) that differed substantially from those in previous research. Two findings supported the theory. First, participants retrieved more private self-cognitions when the private self rather than the collective self was primed; but retrieved more collective self-cognitions when the collective self rather than the private self was primed. Second, people were more likely to retrieve a private self-cognition following another private self-cognition than following a collective one, but were more likely to retrieve a collective self-cognition following another collective one than following a private one.

Formal Lessons Improve Informal Educational Experiences: The Influence of Prior Knowledge on Student Engagement

Educational experiences can be influenced by novel experiences, yet educators often overlook the influence novelty exerts on students. This quasi-experimental study manipulated prior knowledge before a zoo field trip for 210 urban 7^th-grade students from 2 schools, 1 comprised mostly of low-socioeconomic status (SES) families and 1 comprised mostly of middle-SES families. Students participated in 1 of 2 preparatory lessons, only 1 of which previewed field trip-related content, thereby increasing prior knowledge for half the students from each school. Prior knowledge significantly increased learner engagement, measured through attentiveness, from both schools, but in different types of behaviors. Students from the low-SES school demonstrated more attentiveness if their preparatory lesson previewed field trip material than if it was unrelated to the field trip. Students from the middle SES school displayed the same level of attentiveness in both conditions (and overall higher than the low-SES students). This study highlights complexities associated with prior knowledge and reveals strategies to help improve engagement levels for students visiting informal learning environments.     

A Social Learning Perspective on Childhood Trauma and Same‐Sex Intimate Partner Violence

The family violence and childhood trauma literature has suggested that early adverse experiences create risk factors for intimate partner violence (IPV). Thus, this study used a sample of lesbian, gay, and bisexual (LGB) college students (N = 266) to explore differences among childhood trauma, same‐sex IPV, and IPV acceptance. The authors used survey methodology and multivariate analysis of variance. Results indicated that LGB individuals reporting childhood trauma also reported higher rates of IPV, suggesting implications for research and practice.     

A mechanistic perspective on canonical neural computation

Although it has been argued that mechanistic explanation is compatible with abstraction (i.e., that there are abstract mechanistic models), there are still doubts about whether mechanism can account for the explanatory power of significant abstract models in computational neuroscience. Chirimuuta has recently claimed that models describing canonical neural computations (CNCs) must be evaluated using a non-mechanistic framework. I defend two claims regarding these models. First, I argue that their prevailing neurocognitive interpretation is mechanistic. Additionally, a criterion recently proposed by Levy and Bechtel to legitimize mechanistic abstract models, and also a criterion proposed by Chirimuuta herself aimed to distinguish between causal and non-causal explanation, can be employed to show why these models are explanatory only under this interpretation (as opposed to a purely mathematical or non-causal interpretation). Second, I argue that mechanism is able to account for the special epistemic achievement implied by CNC models. Canonical neural components contribute to an integrated understanding of different cognitive functions. They make it possible for us to explain these functions by describing different mechanisms constituted by common basic components arranged in different ways.     

Psychological type and sex differences among church leaders in the United Kingdom

A sample of 135 female and 164 male church leaders of mixed denominations completed the Francis Psychological Type Scales. The female church leaders demonstrated clear preferences for extraversion over introversion, for sensing over intuition, for feeling over thinking, and for judging over perceiving. The male church leaders demonstrated clear preferences for introversion over extraversion, for sensing over intuition, for thinking over feeling, and for judging over perceiving. The predominant type among the women was ESFJ (22%) and the predominant type among the men was ISTJ (30%). Extravert and feeling types were significantly overrepresented among female church leaders, compared with male church leaders.     

How semantic categorization influences inhibitory processing in middle-childhood: an Event Related Potentials study

Throughout middle-childhood, inhibitory processes, which underlie many higher order cognitive tasks, are developing. Little is known about how inhibitory processes change as a task becomes conceptually more difficult during these important years. In adults, as Go/NoGo tasks become more difficult there is a systematic decrease in the P3NoGo response, indicating the use of effective inhibitory strategies (Maguire et al., 2009). This paper investigates the age at which children employ similar inhibitory strategies by studying behavioral and Event Related Potential (ERP) measures of response inhibition for three Go/NoGo tasks. Seventeen 7-8 year-olds and twenty 10-11-year-olds completed three Go/NoGo tasks that differed in the level of categorization necessary to respond. Both age groups displayed slower reaction times as the tasks became more difficult. Further, both groups displayed the predicted Go vs. NoGo P3 amplitude differences in the two simplest tasks, but no significant P3 differences for the most complex task. The reason for this pattern of responses was different in the different age groups. Similar to adults in previous work, the oldest children showed an attenuation of the P3 NoGo response with task difficulty, and no corresponding changes in the Go amplitude. The younger children displayed the opposite pattern, a significant increase in the Go amplitude with task difficulty, and no changes in the NoGo response. These response patterns indicate that efficient inhibitory strategies are developing throughout middle-childhood.
