Cognitive and Behavioural Attention in Children with Low-Moderate and Heavy Doses of Prenatal Alcohol Exposure: a Systematic Review and Meta-analysis

Neuropsychology Review - Attention problems are thought to be a hallmark feature of prenatal alcohol exposure (PAE). Despite decades of research however, these findings have never been pooled to...     

Conceptualizing Self-determination from a Behavioral Perspective: The Role of Choice,Self-control,and Self-management

The goal of education can be defined in many ways; but in searching the literature, we found that in most cases, people consider the goal of education to be developing a self-determined individual. Self-determination is an abstract term. Behavior analysts may find this term difficult to define. Therefore, it may be difficult to observe and measure whether “self-determined behaviors” have developed. Many other service providers use this term frequently; thus, behavior analysts working with these service providers must come to terms with this concept in order to better collaborate. We argue that self-determination can be operationally defined with the concepts of choice, self-control, and self-management. By using the measurable behaviors included in these concepts, we believe that services can be developed to teach self-determination skills. This paper explores these concepts and how they can contribute to an operational definition of self-determination, and ultimately, help behavior analysts work with other providers to effectively teach self-determination to individuals with developmental disabilities.

     

Interhemispheric communication via direct connections for alternative meanings of ambiguous words

A priming experiment was used to investigate Burgess and Simpson's (1988) claim that interhemispheric cooperation plays an essential role in the interpretation of ambiguous text. In doing so, the merits of two models of interhemispheric cooperation, the homotopic inhibition theory (Cook, 1986) and the direct connections model (Collins & Coney, 1998), were examined. Priming of alternative meanings of ambiguous words was measured using homographs and their dominant (e.g., BARK-DOG) and subordinate meanings (e.g., BARK-TREE) as related pairs in a lexical decision task, with normal university students as subjects. Stimulus pairs were temporally separated by stimulus onset asynchronies (SOAs) of 180 and 350 ms and were independently projected to the left or right visual fields (LVF or RVF). At the shorter SOA, priming was restricted to LVF-RVF presentations, with homograph primes directed to the LVF equally facilitating responses to RVF targets which were associated with their dominant and subordinate meanings. This suggests that within 180 ms, a homograph projected to the right hemisphere activates a range of alternative meanings in the left hemisphere. At an SOA of 350 ms, LVF-RVF priming was obtained along with RVF-LVF and RVF-RVF priming. Evidently at this stage of processing, an ambiguous word directed to either hemisphere activates a range of alternative meanings in the contralateral hemisphere, while RVF primes also activate subordinate, but not dominant meanings in the left hemisphere. A homograph directed to the LVF did not activate dominant or subordinate meanings within the right hemisphere at either SOA. Generally, ambiguous words directed to either hemisphere activated a more extensive array of meanings in the contralateral hemisphere than in the hemisphere to which the prime was directed. This confirms the importance of interhemispheric cooperation in generating alternate meanings of ambiguous words. Strong support was found for the direct connections model (Collins & Coney, 1998), but no support for the homotopic inhibition theory (Cook, 1986).     

A conceptual model of cultural predictors of anxiety among Japanese American and part-Japanese American adolescents

A model integrating Japanese ethnicity, cultural identity, and anxiety was developed and assessed in Japanese American and part-Japanese American high school seniors (N = 141). Using measures from the Hawaiian High Schools Health Survey, the model incorporated the State-Trait Anxiety Inventory, the Major Life Events Scale, and the Japanese Culture Scale (JCS). Japanese American adolescents scored higher on the JCS and reported fewer anxiety symptoms than part-Japanese American adolescents. Predictors for anxiety were being Japanese American versus part-Japanese American, income, and culturally intensified events. A significant interaction of behavior by self-identification was obtained. The model had good overall fit, suggesting that cultural identity formation may contribute to anxiety experienced particularly by adolescents of mixed heritage.     

A safe haven: an attachment theory perspective on support seeking and caregiving in intimate relationships

This study used an attachment theoretical framework to investigate support-seeking and caregiving processes in intimate relationships. Dating couples (N = 93) were videotaped while one member of the couple (support seeker) disclosed a personal problem to his or her partner (caregiver). Results indicated that when support seekers rated their problem as more stressful, they engaged in more direct support-seeking behavior, which led their partners to respond with more helpful forms of caregiving. Responsive caregiving then led seekers to feel cared for and to experience improved mood. Evidence for individual differences was also obtained: Avoidant attachment predicted ineffective support seeking, and anxious attachment predicted poor caregiving. Finally, couples in better functioning relationships engaged in more supportive interactions, and participants' perceptions of their interaction were biased by relationship quality and attachment style.     

Personality correlates of heroic rescue during the holocaust

This study investigated the extent to which personality variables can be used to discriminate non-Jewish heroes of the Holocaust from bystanders and from a comparison group of prewar European immigrants who left their countries of origin prior to World War II. Eighty verified rescuers, 73 bystanders, and 43 immigrants were administered measures of locus of control, autonomy, risk taking, social responsibility, tolerance/authoritarianism, empathy, and altruistic moral reasoning. A three-group discriminant function analysis was able to correctly classify 80.2% of the sample by a combination of personality and demographic variables. When the bystanders and immigrants, who differed very little from each other, were grouped together and compared to the rescuers, the personality variables alone correctly classified 93.1% of the sample. Implications regarding the relationship between personality and altruistic behavior, as well as suggestions for future research are discussed.     

Borderline personality features predict alcohol use problems

This study assessed the relation between BPD features and problems associated with alcohol use 2 years later in young adults. Approximately 5,000 nonclinical young adults were screened for BPD features, and two cohorts of participants completed the laboratory phase of the study at Time 1 (total N = 421) and then again 2 years later at Time 2 (total N = 356). Measures included self-report and interview-based assessments of personality disorders, psychopathology in biological parents, Axis I psychopathology, and alcohol use problems. BPD features were found to significantly predict alcohol use problems 2 years later after controlling for parents' substance use disorders, Axis I psycho-pathology (including alcohol abuse/dependence), and non-BPD personality disorders. In addition, the BPD subscale that assesses impulsivity was found to be significantly associated with alcohol use problems once all predictors were entered into the model.
