Pictorial superiority effects in oldest-old people

We examined memory for pictures and words in middle-age (45-59 years), young-old (60-74 years), old-old (75-89 years), and the oldest-old adults (90-97 years) in the Louisiana Healthy Aging Study. Stimulus items were presented and retention was tested in a blocked order where half of the participants studied 16 simple line drawings and the other half studied matching words during acquisition. Free recall and recognition followed. In the next acquisition/test block a new set of items was used where the stimulus format was changed relative to the first block. Results yielded pictorial superiority effects in both retention measures for all age groups. Follow-up analyses of clustering in free recall revealed that a greater number of categories were accessed (which reflects participants' retrieval plan) and more items were recalled per category (which reflects participants' encoding strategy) when pictures served as stimuli compared to words. Cognitive status and working memory span were correlated with picture and word recall. Regression analyses confirmed that these individual difference variables accounted for significant age-related variance in recall. These data strongly suggest that the oldest-old can utilise nonverbal memory codes to support long-term retention as effectively as do younger adults.     

Patients’ Initial Doubts, Reservations and Objections to the ABC’s of REBT and their Application

This exploratory research set out to develop an initial framework and categorization scheme for understanding patients’ initial doubts, reservations and objections to the ABC’s of REBT and their application. 60 patients were asked to write down their doubts following a pre-therapy “Introduction to REBT” session. Subsequently, an emergent content analysis was carried out to identify main themes. The content analysis revealed five general categories, of which the two largest ones concerned theoretical doubts about the ABC model, and doubts about putting the ABC model into practice. Further sub-categorization revealed a variety of concerns that related to these categories. For example, a large proportion of doubts about putting the ABC model into practice were sub-categorized as concerning the perceived difficulty of doing so. In turn, this sub-category contained further sub-categories of difficulty-related beliefs.

RT distributional analysis of cognitive-control-related brain activity in first-episode schizophrenia

Impairments in cognitive control are a defining feature of schizophrenia. Aspects of cognitive control include proactive control—the maintenance of task rules or goals to bias attention and maintain preparedness—and reactive control—the engagement of attention in reaction to changing cognitive demands. Proactive control is thought to be particularly impaired in schizophrenia. We sought to examine proactive and reactive control in schizophrenia, as measured by reaction time (RT) variability, and especially long RTs, which are thought to represent lapses in proactive control, during the Stroop paradigm. Furthermore, we sought to examine the neural underpinnings of lapses in proactive control and the subsequent engagement of reactive control in those with schizophrenia, as compared to healthy controls, using fMRI. We found that patients with schizophrenia displayed greater RT variability and more extremely long RTs than controls suggesting that proactive control was weaker in the schizophrenia than in the control group. All of the subjects engaged regions of the cognitive control network during long RTs, consistent with an engagement of reactive control following a failure in proactive control on these trials. The schizophrenia group, however, displayed significantly diminished activity in these regions relative to controls. Our results suggest increased failures in proactive control, but also impaired reactive control, in schizophrenia as compared to healthy subjects.     

Relationship influences on teachers' perceptions of academic competence in academically at-risk minority and majority first grade students

This study examined the associations among child demographic variables, teacher perceptions of parent-teacher and student-teacher relationship quality, and teacher perceptions of children's academic abilities in an ethnically diverse sample of 607 academically at-risk first grade children. Relative to relationships with African American children and parents, teachers rated their relationships with White and Hispanic children and parents more positively. Measures of relationship quality added unique variance to teachers' perceptions of children's abilities, controlling for parent educational level and measured ability. Relationship variables fully mediated the association between African American status and teachers' perceptions of children's abilities. Implications of the findings for teacher in-service and professional development and for parent involvement programs are discussed.     

Religion and the Acceptability of White‐Collar Crime: A Cross‐National Analysis

This article examines whether shared religious beliefs and religious social relationships (Durkheim) and belief in a personal, moral God (Stark) negatively affect attitudes toward the acceptability of white‐collar crime. In addition, using a large cross‐national sample and estimating multilevel models, we test whether effects are conditional on modernization and religious contexts characterized by belief in an impersonal or amoral God. Shared religious beliefs and the importance of God in one's life are negatively related to the acceptability of white‐collar crime. These effects, however, weaken in religious contexts characterized by belief in an impersonal or amoral God as do the effects of religious social relationships and belonging to a religious organization; modernization, on the other hand, does not have a moderating effect. In short, religious belief is associated with lower acceptance of white‐collar crime and certain types of religious contexts condition this relationship.     

Distinguishing indeterminate belief from “risk-averse” preferences

I focus my discussion on the well-known Ellsberg paradox. I find good normative reasons for incorporating non-precise belief, as represented by sets of probabilities, in an Ellsberg decision model. This amounts to forgoing the completeness axiom of expected utility theory. Provided that probability sets are interpreted as genuinely indeterminate belief (as opposed to “imprecise” belief), such a model can moreover make the “Ellsberg choices” rationally permissible. Without some further element to the story, however, the model does not explain how an agent may come to have unique preferences for each of the Ellsberg options. Levi (1986, Hard choices: Decision making under unresolved conflict. Cambridge, New York: Cambridge University Press) holds that the extra element amounts to innocuous secondary “risk” or security considerations that are used to break ties when more than one option is rationally permissible. While I think a lexical choice rule of this kind is very plausible, I argue that it involves a greater break with xpected utility theory than mere violation of the ordering axiom.     

Active avoidance conditioning in zebrafish (Danio rerio)

The zebrafish represents a potentially useful organism for studying genes involved in learning and memory function in vertebrates, because a number of genetic techniques in zebrafish have been developed to produce a wide variety of genetic mutants. While zebrafish mutants are being developed, behavioral studies on learning and memory function in zebrafish are in urgent need. The present study investigated active avoidance conditioning in normal zebrafish. Zebrafish were trained to swim from a lighted (CS) compartment to a dark compartment to avoid an electrical body shock (US) in a shuttle-box that consisted of a water-filled tank separated by an opaque barrier into two equal compartments. By varying the number of trials per training session and the duration of the intertrial interval, Experiments 1 and 2 showed that, with the CS, US, and intertrial interval being 12s, zebrafish learned avoidance responses within a training session consisting of 30 trials and retained the avoidance responses. Experiment 3 showed that zebrafish learned avoidance responses following the association between the CS of light and the US of shock in the avoidance conditioning paradigm. Using the avoidance conditioning paradigm, Experiment 4 investigated the amnestic effects of N-methyl-D-aspartate receptor antagonist MK-801 and nitric oxide synthase inhibitor L-NAME in zebrafish. Experiment 4 showed that post-training injection of L-NAME significantly impaired retention of avoidance responses while MK-801 did not, confirming previous results with other vertebrates. The results of the present study suggest the similar involvements of neurochemicals in learning and memory among vertebrates. Thus, future studies with zebrafish mutants may identify genes involved in learning and memory in vertebrates.     

Caring for Someone with Depression: Attitudes and Clinical Practices of Australian Mental Health Workers

Many people who support a person with depression report struggling with the carer role and being dissatisfied with the inclusivity and lack of support provided by clinicians. However, little is known about what influences the support provided to Australian carers of people with depression. To investigate this, 119 Australian mental health workers completed a self‐report questionnaire to gather information on their attitudes towards, barriers experienced and current clinical practices when working with carers of people with depression. Participants' attitudes towards family members and carers were generally positive. Reported inclusive clinical practices varied. Participants identified a number of barriers to inclusive practice that were predominantly organisational in nature. Participants who perceived more barriers reported providing more clinical interventions. Attitudes and barriers were associated with the inclusive clinical practice of participants who worked with mental health consumers, but not participants who worked with family members and carers. Even among this sample of self‐selecting clinicians, there was room for significant improvement in rates of carer inclusive practice. Further research should explore not only what inhibits but also what enables the participation of family members and carers in the care and treatment process for people with depression.     

Barriers Impacting the Utilization of Supervision Techniques in Genetic Counseling

Clinical supervision is an essential element in training genetic counselors. Although live supervision has been identified as the most common supervision technique utilized in genetic counseling, there is limited information on factors influencing its use as well as the use of other techniques. The purpose of this study was to identify barriers supervisors face when implementing supervision techniques. All participants (N?=?141) reported utilizing co-counseling. This was most used with novice students (96.1 %) and intermediate students (93.7 %). Other commonly used techniques included live supervision where the supervisor is silent during session (98.6 %) which was used most frequently with advanced students (94.0 %), and student self-report (64.7 %) used most often with advanced students (61.2 %). Though no barrier to these commonly used techniques was identified by a majority of participants, the most frequently reported barriers included time and concern about patient’s welfare. The remaining supervision techniques (live remote observation, video, and audio recording) were each used by less than 10 % of participants. Barriers that significantly influenced use of these techniques included lack of facilities/equipment and concern about patient reactions to technique. Understanding barriers to implementation of supervisory techniques may allow students to be efficiently trained in the future by reducing supervisor burnout and increasing the diversity of techniques used.
