Evaluation of a trial-based interview-informed synthesized contingency analysis

We evaluated the viability of an interview-informed synthesized-contingency analysis (IISCA) conducted in a trial-based format with 3 children with autism spectrum disorders who engaged in problem behavior. We compared results to those from typical trial-based and traditional functional analyses and found high degrees of correspondence. The trial-based IISCA format took the least amount of time to conduct and was associated with the lowest frequencies of problem behavior. Results are discussed in terms of merits of each of the 3 types of functional analysis arrangements and directions for future research.     

A Dyadic IRT Model

Psychometrika - We propose a dyadic Item Response Theory (dIRT) model for measuring interactions of pairs of individuals when the responses to items represent the actions (or behaviors,...     

EARSHOT: A Minimal Neural Network Model of Incremental Human Speech Recognition

Despite the lack of invariance problem (the many-to-many mapping between acoustics and percepts), human listeners experience phonetic constancy and typically perceive what a speaker intends. Most models of human speech recognition (HSR) have side-stepped this problem, working with abstract, idealized inputs and deferring the challenge of working with real speech. In contrast, carefully engineered deep learning networks allow robust, real-world automatic speech recognition (ASR). However, the complexities of deep learning architectures and training regimens make it difficult to use them to provide direct insights into mechanisms that may support HSR. In this brief article, we report preliminary results from a two-layer network that borrows one element from ASR, long short-term memory nodes, which provide dynamic memory for a range of temporal spans. This allows the model to learn to map real speech from multiple talkers to semantic targets with high accuracy, with human-like timecourse of lexical access and phonological competition. Internal representations emerge that resemble phonetically organized responses in human superior temporal gyrus, suggesting that the model develops a distributed phonological code despite no explicit training on phonetic or phonemic targets. The ability to work with real speech is a major advance for cognitive models of HSR.     

Why People Join Terrorist Groups in Kuwait: A Qualitative Examination

Qualitative interviews were conducted with nine members of the Islamic State of Iraq and Syria (ISIS) and Al-Qaeda currently incarcerated in Kuwait's Central Prison. The semistructured interviews attempted to understand psychosocial factors in Kuwait that contributed to their decision to join extremist organizations. Interviews were analyzed using Interpretive Phenomenological Analysis (IPA) and the emergent themes identified the following core themes explaining their involvement: (1) religious identity development; (2) personal connections; (3) propaganda; (4) defense of Islam; and (5) social marginalization. Participants described a process whereby their religion became a central part of their personal identity. As their religious identity developed, they became involved in Islamic organizations where they met people involved with ISIS or Al-Qaeda. These social connections exposed them to jihadi propaganda which, in addition to increased military conflict in the Middle East, crystallized their beliefs that Islam is under attack, and they were religiously obligated to defend it. The results also identified societal factors that increased the probability of engaging in terrorism including relatively low levels of education, coming from low socioeconomic groups in Kuwait, and feeling socially marginalized by broader Kuwaiti society.     

Changing counterproductive beliefs about attention,memory, and multitasking: Impacts of a brief,fully online module

Ubiquitous mobile technology is part of contemporary life, bringing with it the potential for distraction and reduction in performance associated with multitasking. The predisposition toward dysfunctional multitasking may be shaped in part by beliefs that individuals hold about memory and attention. The issue is particularly pressing for college students, given established links between distraction, multitasking, and learning. This project assessed the impact of an online learning module on beliefs about attention, memory, and learning in college students. It also contrasted these beliefs in a college and non-college community sample. Significant reductions in counterproductive beliefs were associated with completing the module; counterproductive beliefs were also no more prevalent in the college vs. the non-college sample. Our findings suggest that brief online modules are a practical way to address counterproductive beliefs related to multitasking with technology, and add to the literature on metacognition, attention, and multitasking in college and non-college populations.     

Severe traumatic brain injury: some effects on family caregivers

This study assesses the effects of severe traumatic brain injuries on family members and functioning-a topic of interest for those working with survivors and their families. This issue is receiving increased attention as recent findings suggest that family adjustment influences outcome for brain-injured persons. The Family Environment Scale and the Profile of Mood States were completed by 25 individuals who had a family member with a severe traumatic brain injury. These scales were also completed by a comparison group of 32 individuals who had no brain-injured family member. In terms of family functioning, the findings suggest that, when a family member suffers a severe traumatic brain injury, depression may be elevated, along with a decreased ability to express feelings, decreased time and energy for social and recreational activities, and increased control in comparison to families without a brain-injured member. While this might contribute to family isolation which could last for many years, the overall finding of the present study was that caregiver families were coping adequately.     

Perceptions of another person's heavy drinking as a function of one's relationship to the drinker a pilot study

Of 301 participants in a telephone survey, 201 could identify a problem drinker within their social networks. In 67 cases the drinker was a partner, in 45 another family member, in 61 a friend, and in 28 a work colleague. Another person's heavy drinking was reported as most disrupting to one's life when that person was a partner or other family member or if one was living in the same residence as the drinker. The exception to this was that reported disruption to respondents' work life was greatest when the drinker was a work colleague. While there appear to be problems for friends and work colleagues, partners and other family members appear to report the most disruption so providing services to family members seems appropriate.
