Memory retrieval and discrimination learning

A better reinforcement schedule may be associated with one exteroceptive stimulus (S+) than with another exteroceptive stimulus (S−). While all theories agree that performance in such discrimination tasks is affected by the reinforcement schedules associated with the exteroceptive S+ and S− cues, some theories suggest that performance is also affected by the reinforcement schedule associated with interoceptive reward produced cues. The two experiments reported here were concerned with identifying the conditions under which the interoceptive cues produced by nonreward come to affect performance. According to one hypothesis, such cues will acquire control over approach responding if animals make an approach response in their presence, but not otherwise. According to the memory hypothesis, the memory of nonreinforcement will become a signal for reinforcement, thus invigorating performance, if it is retrieved on a rewarded trial. In two experiments, two groups made strong approach responses to the nonreinforced cues on S− trials, but the memory of nonreward was better retrieved on a subsequent rewarded trial in one group than in the other. Subsequently, both groups were extinguished. The extinction findings support the memory view.     

Indero: Intergenerational Trauma and Resilience between Burundian Former Child Soldiers and Their Children

Since many former child soldiers are aging and having children of their own, this study aimed to understand how the effects of trauma are passed to the next generation. In this qualitative study, semistructured interviews, focus groups, and observations were conducted with 25 former child soldiers and 15 matched civilian parents. Analysis used a grounded‐theory approach. Trauma may be transmitted from former child soldiers to their offspring via (a) the effect on indero (how to raise a child); (b) severe parental emotional distress; and (c) community effects. Incorporating themes of indero values on how to raise children, the effects of parental posttraumatic stress and depressive symptoms on offspring, and the stigma associated with the families of former child soldiers may provide key areas of intervention in mental healing.     

Birth Defects,Causal Attributions,and Ethnicity in the National Birth Defects Prevention Study

In order to translate research findings into effective prevention strategies, it is important to understand people's beliefs about the causes of poor health outcomes. However, with the exception of knowledge and beliefs about folic acid supplementation, little is known regarding women's causal attributions women regarding birth defects. We employed Attribution Theory constructs to analyze open-text interview responses from 2,672 control mothers in the National Birth Defects Prevention Study who gave birth in 1997–2005. Common themes included use of alcohol, tobacco, illicit drugs, and medications during pregnancy. Stress and emotional upset were also suggested as possible causes of birth defects. Genetic- and heredity-related responses were more likely to be mentioned by Asian/Pacific Islander women compared to non-Hispanic Whites. Hispanic women were less likely to suggest several specific possible teratogens, such as paint, pesticides, or other chemicals, but were more likely to suggest events occurring during childbirth. Differences also emerged among ethnic groups for theoretical constructs, although most responses were categorized as controllable, changeable over time, and with an internal locus of causality.     

Relations Between Contextual Performance,Personality, and Occupational Advancement

Two studies investigated relations between supervisors' evaluations of contextual performance and personality characteristics in jobs where opportunities for advance- ment were either absent or present. The first study examined performance in entry- level jobs where advancement, in general, was precluded; employees (N = 214) completed the Hogan Personality Inventory (HPI) as applicants and subsequently were rated by their supervisors for contextual performance. Results indicated that conscientiousness-measured by HPI Prudence scores-was significantly related to ratings of Work Dedication and Interpersonal Facilitation, which are dimensions of contextual performance. The results were corroborated in an independent sample. In the second study, employees (N = 288) in jobs with opportunities for advancement completed the HPI and their supervisors provided ratings for contextual performance. Results indicated that ambitiodsurgency-measured by HPI Ambition scores-pre- dicted contextual performance. These results also were confirmed in a second sample. Relations between personality and contextual performance are explained by the motives of cooperation-getting along-and status-getting ahead.     

Spiritual Care in the ICU: Perspectives of Dutch Intensivists,ICU Nurses,and Spiritual Caregivers

Since there are no scientific data available about the role of spiritual care (SC) in Dutch ICUs, the goal of this quantitative study was twofold: first, to map the role of SC as a part of daily adult ICU care in The Netherlands from the perspective of intensivists, ICU nurses, and spiritual caregivers and second, to identify similarities and differences among these three perspectives. This study is the quantitative part of a mixed methods approach. To conduct empirical quantitative cohort research, separate digital questionnaires were sent to three different participant groups in Dutch ICUs, namely intensivists, ICU nurses, and spiritual caregivers working in academic and general hospitals and one specialist oncology hospital. Overall, 487 participants of 85 hospitals (99 intensivists, 290 ICU nurses, and 98 spiritual caregivers) responded. The majority of all respondents (>70%) considered the positive effects of SC provision to patients and relatives: contribution to mental well-being, processing and channeling of emotions, and increased patient and family satisfaction. The three disciplines diverged in their perceptions of how SC is currently evolving in terms of information, assessment, and provision. Nationwide, SC is not implemented in daily ICU care. The majority of respondents, however, attached great importance to interdisciplinary collaboration. In their view SC contributes positively to the well-being of patients and relatives in the ICU. Further qualitative research into how patients and relatives experience SC in the ICU is required in order to implement and standardize SC as a scientifically based integral part of daily ICU care.     

Enabled or disabled? Working parents of disabled children and the provision of child‐care

This research explores the reported experiences of working parents of disabled children with respect to formal and informal sources of child‐care, the need for which extends beyond the childhood years. Forty families with at least one disabled child, representing a variety of family structures and work situations, participated in semi‐structured interviews. The resultant data revealed an analytical axis of disabling and enabling features of child‐care. These are illustrated here with reference to the parents' accounts. Disabling barriers were physical, attitudinal or material. However, some features of either formal or informal care served to dismantle these barriers. Where formal child‐care was available, appropriate, flexible and accommodating to the needs of both the parents and the disabled child, the parents reported being able to combine working and caring roles successfully. However, where formal supports were inadequate or non‐existent, parents who could rely on the support of family and friends to supply emotional and instrumental assistance reported balance between work and caring roles. Whilst all parents need satisfactory child‐care in the early years, these parents' needs extend beyond the childhood years: the parents' accounts highlighted their complex and long‐term child‐care needs. Options for further research were proposed which would emphasize negotiation within families over time, or would focus on intersections of other parts of the work‐family‐community system.

The role of instrumental responses in memory retrieval in a T-maze

Retrieval of the memory of non-reward on a rewarded trial was investigated here employing rats in a T-maze. A forced choice procedure was used. The daily rewarded (R) and non-rewarded (N) trials always occurred in a fixed order, two R, four N, and finally two R, i.e. the series was R1-R2-N1-N2-N3-N4-R3-R4. In an original acquisition phase, Trial N4 of the series having occurred in a particular spatial alternative, e.g. left, it was followed by R3 either in the same alternative, Groups C and T, or in the opposite alternative, Group R. Group T, unlike Groups C and R, received a relatively long intertrial interval between N4 and R3. In a shift phase, groups were treated as in original acquisition except that the long intertrial interval (Group T) and the change in response (Group R) now occurred between R3 and R4 rather than N4 and R3. The major finding in original acquisition was slower running by Groups T and R than by Group C on Trials N2, N3, and N4. In shift, differences between the groups disappeared. These findings are consistent with the hypothesis that response-produced cues contribute to memory retrieval.     

Intellectual ability, learning style, personality, achievement motivation and academic success of psychology students in higher education

This study is directed towards an integration of intellectual ability, learning style, personality and achievement motivation as predictors of academic success in higher education. Correlational analyses partly confirmed and partly disconfirmed our expectations in a sample of 409 first-year psychology students. Consistent with the literature, intellectual ability and achievement motivation were associated positively with academic success. For the meaning directed, reproduction directed and application directed learning style, no positive association with academic success could be detected. The undirected learning style, however, appeared to be a consistent negative predictor. For the Big Five personality factors (extraversion, agreeableness, conscientiousness, neuroticism and openness to experience), a consistent, positive association for conscientiousness with academic success was found. The very first examination at the university came out as the most important predictor for academic success, even after two and three years of study. The implications of the results are discussed in relation to the literature and the policy of the Dutch Ministry of Education.
