Acute effects of alcohol on memory: Impact of emotional context and serial position

Although the amnestic effects of alcohol in humans are well known, its effects on emotional memory are unclear. In this study, using a randomized double-blind placebo-controlled design, we examine narrative emotional episodic memory in healthy human female volunteers (n = 32) who received either a single dose of alcohol (0.6 g/kg), or a placebo and then viewed neutral story elements presented in either a neutral or emotional context. Memory was tested for gist and detail of the neutral elements 3 days later in a surprise recognition test. Since alcohol modulates GABAergic neurotransmission and may exert its effects on emotion through the limbic system, we predicted that acute alcohol treatment would reduce the expected emotional memory-advantage for gist, leaving detail memory relatively unaffected. Furthermore, given previous findings showing that ‘primacy’ memory is enhanced by physiological arousal, we predicted that reduced arousal produced by alcohol would have the opposite effect and impair primacy memory relative to the middle or ‘recency’ sections of the narrative. Emotional arousal was expected to oppose this effect, so impaired primacy memory following alcohol was only expected in the neutral version of the narrative. Although there was a main effect of story phase (though not of story version), contrary to expectations, alcohol impaired primacy memory for emotionally encoded neutral material. The results suggest that under certain circumstances emotional context or physiological arousal make memories labile and susceptible to disruption through pharmacological manipulation during encoding.     

Estimating individual treatment effects from multiple-baseline data: A Monte Carlo study of multilevel-modeling approaches

While conducting intervention research, researchers and practitioners are often interested in how the intervention functions not only at the group level, but also at the individual level. One way to examine individual treatment effects is through multiple-baseline studies analyzed with multilevel modeling. This analysis allows for the construction of confidence intervals, which are strongly recommended in the reporting guidelines of the American Psychological Association. The purpose of this study was to examine the accuracy of confidence intervals of individual treatment effects obtained from multilevel modeling of multiple-baseline data. Monte Carlo methods were used to examine performance across conditions varying in the number of participants, the number of observations per participant, and the dependency of errors. The accuracy of the confidence intervals depended on the method used, with the greatest accuracy being obtained when multilevel modeling was coupled with the Kenward—Roger method of estimating degrees of freedom.     

Right Motive, Wrong Action: Direct Consequentialism and Evaluative Conflict

In this paper I look at attempts to develop forms of consequentialism which do not have a feature considered problematic in Direct Consequentialist theories (that is, those consequentialist theories that apply the criterion of rightness directly in the evaluation of any set of options). The problematic feature in question (which I refer to as ‘evaluative conflict’) is the possibility that, for example, a right motive might lead an agent to perform a wrong act. Theories aiming to avoid this phenomenon must argue that causal relationship entails motives and acts (for example) having the same moral status. I argue that attempts to ensure such ‘evaluative consistency’ are themselves deeply problematic, and that we must therefore accept evaluative conflict.     

Self-objectification and ideal body shape for men and women

Objectification theory posits that valuing one's body for appearance rather than performance is associated with a range of negative psychological outcomes. This theory has been tested in women, but has received less empirical attention in men. This study examined the relation between self-objectification and ideal body shape in both men and women. One hundred eighty-three college students (111 women, 72 men) completed a questionnaire containing measures of self-objectification and ideal body shape (using a figure array ranging from non-muscular to very muscular). Consistent with hypotheses, women desired a less muscular body and men desired a more muscular body. Women also self-objectified more than men. In addition, there was an interaction between sex and self-objectification on ideal body shape. For women, higher self-objectification scores were related to a desire for a less muscular body. For men, higher self-objectification scores were related to a desire for a more muscular body. Self-objectification theory is a useful framework for understanding body image issues in men. However, the relation between self-objectification and other body related variables may differ for men and women.     

Correct Responses and the Priority of the Normative

The ‘Wrong Kind of Reason’ problem for buck-passing theories (theories which hold that the normative is explanatorily or conceptually prior to the evaluative) is to explain why the existence of pragmatic or strategic reasons for some response to an object does not suffice to ground evaluative claims about that object. The only workable reply seems to be to deny that there are reasons of the ‘wrong kind’ for responses, and to argue that these are really reasons for wanting, trying, or intending to have that response. In support of this, it is pointed out that awareness of pragmatic or strategic considerations, unlike awareness of reasons of the ‘right kind’, are never sufficient by themselves to produce the responses for which they are reasons. I argue that this phenomenon cannot be used as a criterion for distinguishing reasons-for-a-response from reasons-for-wanting-to-have-a-response. I subsequently investigate the possibility of basing this distinction on a claim that the responses in question (e.g. admiration or desire) are themselves inherently normative; I conclude that this approach is also unsuccessful. Hence, the ‘direct response’ phenomenon cannot be used to rule out the possibility of pragmatic or strategic reasons for responses; and the rejection of such reasons therefore cannot be used to circumvent the Wrong Kind of Reason Problem.

Further evaluation of latency measures in the assessment and treatment of severe self‐injurious behavior

Recent research has demonstrated the utility of latency measures during the functional analysis of problem behavior; however, few studies have evaluated the utility of latency measures during subsequent treatment analyses. The current study seeks to extend the literature on the use of latency measures during the treatment of severe self‐injurious behavior (SIB). Following a latency‐based functional analysis, a treatment analysis was conducted using a hybrid procedure in which baseline sessions were terminated following the first instance of SIB, and test sessions ended after a fixed length of time. Latency to SIB was compared across conditions, whereas latency and rate measures for both SIB and functional communication responses were compared for the functional communication training condition. Results suggest that latency measures may be too sensitive during treatment analyses and that it is beneficial to use a hybrid procedure that allows for both latency and rate comparisons.     

Parent and Child Anxiety Sensitivity: Relationship in a Nonclinical Sample

Little is known about the relationship between parent and child anxiety sensitivity (AS), particularly in nonclinical samples. The present study examined this association in 207 healthy parent-child pairs including 244 children (mean age = 12.3 years, 103 girls) and 226 parent figures (175 mothers). Sequential multiple linear regression revealed that parent AS was significantly associated with child AS in girls, but not in boys. Parent AS accounted for 9% of incremental variance in child AS, after controlling for child age, parent depression, and parent anxiety. Analyses of parent AS dimensions indicated that the social concerns dimension accounted for 14% of incremental variance in child AS in girls only. Parent anxiety and depression showed no association with child AS, once parent AS was taken into account. The findings indicate that parent AS, especially AS social concerns, demonstrates a significant relationship with child AS in this nonclinical sample of girls.     

Communication and social skills in socially anxious and nonanxious individuals in the context of romantic relationships

This study examined differences between socially anxious and nonanxious individuals' ability to use effective communication skills and social skills in the context of romantic relationships. Socially anxious (n = 13) and nonanxious (n = 14) individuals and their romantic partners were videotaped while participating in 10-minute neutral, negative, and pleasant conversations. Regardless of the type of conversation in which they were involved, socially anxious individuals demonstrated impairment in 10 of the 11 social skill variables assessed. In negative conversations, socially anxious individuals displayed more "very negative" behaviors than nonanxious individuals, and across all conversations they displayed fewer "positive" behaviors than nonanxious individuals. Partners of socially anxious and nonanxious individuals did not differ in their communication quality. The results suggest that social anxiety is associated with deficits in relationship maintenance behavior and call for the completion of a larger study examining the interpersonal consequences of social anxiety.     

The father-daughter relationship rating scale

A 9-item scale designed to measure perceived relationships of girls and their fathers is internally consistent (alpha=.89) and showed clear factor structure.     

Relations between life difficulties, measures of working memory operation, and examination performance in a student sample

This study investigated the hypothesis that the negative effect of life difficulties on examination performance in university students (Andrews & Wilding, 2004) can be explained by impairment of working memory efficiency. UK-based students were given an extensive interview covering recent life stressors, and carried out a task testing working memory span, in which they had to judge the truth of arithmetic expressions while retaining words. Students reporting one or more life difficulties in the preceding 12 months recalled significantly fewer words than those reporting no such difficulties, but showed no difference in processing time on the task. However, while the number of words recalled was unrelated to examination performance at the end of the year, students who took longer on the task did significantly less well in the examination. This relation was more marked in Science than in Arts students. A number of possible explanations for this pattern of results are considered, which need to be explored in further research. In particular it is suggested that the number of words retained in the working memory span task reflects current state, and is reduced by intrusive thoughts provoked by current life difficulties, while time on the task reflects more permanent efficiency of the processing system and, therefore, efficiency in study and examinations.
