Contiguity and the causal theory of memory

In Memory: A Philosophical Study, Bernecker argues for an account of contiguity. This Contiguity View is meant to solve relearning and prompting, wayward causation problems plaguing the causal theory of memory. I argue that Bernecker’s Contiguity View fails in this task. Contiguity is too weak to prevent relearning and too strong to allow prompting. These failures illustrate a problem inherent in accounts of memory causation. Relearning and prompting are both causal relations, wayward only with respect to our interest in specifying remembering’s requirements. Solving them requires saying more about remembering, not causation. I conclude by sketching such an account.     

Younger and older adults’ collaborative recall of shared and unshared emotional pictures

Although a group of people working together recalls more items than any one individual, they recall fewer unique items than the same number of people working apart whose responses are combined. This is known as collaborative inhibition, and it is a robust effect that occurs for both younger and older adults. However, almost all previous studies documenting collaborative inhibition have used stimuli that were neutral in emotional valence, low in arousal, and studied by all group members. In the current experiments, we tested the impact of picture-stimuli valence, picture-stimuli arousal, and information distribution in modulating the magnitude of collaborative inhibition. We included both younger and older adults because there are age differences in how people remember emotional pictures that could modulate any effects of emotion on collaborative inhibition. Results revealed that when information was shared (i.e., studied by all group members), there were robust collaborative inhibition effects for both neutral and emotional stimuli for both younger and older adults. However, when information was unshared (i.e., studied by only a single group member), these effects were attenuated. Together, these results provide mixed support for the retrieval strategy disruption account of collaborative inhibition. Supporting the retrieval strategy disruption account, unshared study information was less susceptible to collaborative inhibition than shared study information. Contradicting the retrieval strategy disruption account, emotional valence and arousal did not modulate the magnitude of collaborative inhibition despite the fact that participants clustered the emotional, but not neutral, information together in memory.     

Co-Rumination Exacerbates Stress Generation among Adolescents with Depressive Symptoms

Through stress generation, individuals’ own thoughts and behaviors can actually lead to increases in their experience of stress. Unfortunately, stress generation is especially common among individuals who are already suffering from elevated depressive symptoms. However, despite the acknowledgement that some individuals with depressive symptoms generate greater stress than others, few studies have identified specific factors that could exacerbate stress generation among individuals with depressive symptoms. The present study examines co-rumination as a factor that might exacerbate stress generation among adolescents with depressive symptoms using a short-term longitudinal design. Considering these processes among adolescents was critical given that many youth experience increases in depressive symptoms at this developmental stage and that co-rumination also becomes more common at adolescence. Participants were 628 adolescents (326 girls; 302 boys) who reported on their depressive symptoms, experiences of stress, and co-rumination with a best friend. Interpersonal stressors (peer and family stress) and non-interpersonal stressors (school and sports stress) were assessed. Consistent with past research, adolescents with depressive symptoms experienced greater interpersonal and non-interpersonal stress over time. Importantly, co-rumination interacted with both depressive symptoms and gender in predicting increases in peer stress. Depressive symptoms predicted the generation of peer stress only for girls who reported high levels of co-rumination with friends. Implications for protecting youth with depressive symptoms against stress generation are discussed.     

Predicting Risky Sexual Behavior: the Unique and Interactive Roles of Childhood Conduct Disorder Symptoms and Callous-Unemotional Traits

Conduct disorder (CD) symptoms and callous-unemotional (CU) traits have been shown to be uniquely associated with risky sexual behavior (RSB) in adolescence and early adulthood, yet their interactive role in predicting RSB remains largely unknown. This study aimed to investigate the predictive value of CD symptoms and CU traits, as well as their interaction, on several RSB outcomes in adolescence and early adulthood. A total of 683 participants (41.7 % female, 47.4 % African American) were followed annually and self-reported age of first sexual intercourse, frequency of condom use, pregnancy, contraction of sexually transmitted infections, and engagement in sexual solicitation from grade 7 to 2-years post-high school. CD symptoms predicted age of first sexual intercourse, condom use, and sexual solicitation. CU traits predicted age of first sexual intercourse and pregnancy. Their interaction predicted a composite score of these RSBs such that CD symptoms positively predicted the composite score among those with high levels of CU traits but not among those with low levels of CU traits. The current findings provide information regarding the importance of both CD symptoms and CU traits in understanding adolescent and early adulthood RSB, as well as the benefits of examining multiple RSB outcomes during this developmental period. These findings have implications for the development and implementation of preventive efforts to target these risky behaviors among adolescents and young adults.     

No blank slates: Pre-existing schemas about pharmaceuticals predict memory for side effects

Objectives: Attribution of symptoms as medication side effects is informed by pre-existing beliefs about medicines and perceptions of personal sensitivity to their effects (pharmaceutical schemas). We tested whether (1) pharmaceutical schemas were associated with memory (recall/recognition) for side effect information (2) memory explained the attribution of a common unrelated symptom as a side effect.

Design: In this analogue study participants saw the patient leaflet of a fictitious asthma drug listing eight side effects.

Main outcome measures: We measured recall and recognition memory for side effects and used a vignette to test whether participants attributed an unlisted common symptom (headache) as a side effect.

Results: Participants who perceived pharmaceuticals as more harmful in general recalled fewer side effects correctly (r_{Correct Recall} = ?.273), were less able to differentiate between listed and unlisted side effects (r_{Recognition Sensitivity} = ?.256) and were more likely to attribute the unlisted headache symptom as a side effect (r_{side effect attribution} = .381, ps < .01). The effect of harm beliefs on side effect attribution was partially mediated by correct recall of side effects.

Conclusion: Pharmaceutical schemas are associated with memory for side effect information. Memory may explain part of the association between pharmaceutical schemas and the attribution of unrelated symptoms as side effects.     

‘I think a little bit of a kick is sometimes what you need’: Women’s accounts of whole-body scanning and likely impact on health-related behaviours

Objective: This study was designed to investigate whether whole-body scanning might promote healthy eating and physical activity in women, and to explore the effects of scanning on body image.

Design: Fourteen women aged 22–45 years without histories of eating disorders or whole-body scanning took part in semi-structured interviews before and after scanning. Data were analysed using inductive thematic analysis.

Results: Scans did not look as expected, and participants expressed ‘surprise’ and ‘shock’. Participants focused on perceived negative aspects of their bodies as revealed in scan images, and agreed that women with body concerns would find scans too ‘real’ and ‘raw’. Eleven women who met UK Government physical activity and healthy eating guidelines reported that the scan provided additional motivation to maintain, and in nine cases to increase, those behaviours. Two women who neither exercised nor ate healthily would not increase physical activity or change their diets significantly following scanning.

Conclusion: Whole-body scanning may enable maintenance or even acceleration of physical activity and healthy eating, but is unlikely to be useful in promoting initiation of these behaviours. Participants engaged in unhelpful body critique when viewing scans; scanning needs to be confined to contexts where support is provided, to avoid increasing body-related concerns.     

Linking Workplace Aggression to Employee Well-Being and Work: The Moderating Role of Family-Supportive Supervisor Behaviors (FSSB)

Purpose

The present study examined the moderating effects of family-supportive supervisor behaviors (FSSB) on the relationship between two types of workplace aggression (i.e., patient-initiated physical aggression and coworker-initiated psychological aggression) and employee well-being and work outcomes.

Methodology

Data were obtained from a field sample of 417 healthcare workers in two psychiatric hospitals. Hypotheses were tested using moderated multiple regression analyses.

Findings

Psychiatric care providers’ perceptions of FSSB moderated the relationship between patient-initiated physical aggression and physical symptoms, exhaustion and cynicism. In addition, FSSB moderated the relationship between coworker-initiated psychological aggression and physical symptoms and turnover intentions.

Implications

Based on our findings, family-supportive supervision is a plausible boundary condition for the relationship between workplace aggression and well-being and work outcomes. This study suggests that, in addition to directly addressing aggression prevention and reduction, family-supportive supervision is a trainable resource that healthcare organizations should facilitate to improve employee work and well-being in settings with high workplace aggression.

Originality

This is the first study to examine the role of FSSB in influencing the relationship between two forms of workplace aggression: patient-initiated physical and coworker-initiated psychological aggression and employee outcomes.

     

The Effectiveness of the MMPI-2-RF in Detecting Feigned Mental Disorders and Cognitive Deficits: a Meta-Analysis

A cornerstone of forensic assessments involves the assessment of response styles, including feigning and malingering. As a forensic relevant instrument (FRI), the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) contains embedded overreporting scales that cover the three major domains: feigned mental disorders (i.e., F-r and Fp-r), feigned cognitive impairment (RBS and FBS-r), and feigned medical complaints (Fs). This meta-analytic review of 30 studies examined the effectiveness of various detection strategies and cut scores for the MMPI-2-RF. As an important clinical concern, several feigning scales (F-r, FBS-r, and RBS) exhibited marked elevations (Ms > 80 T) for genuine responders diagnosed with major depressive or somatoform disorders. However, the Fp-r—a true rare-symptoms detection strategy—proved highly effective for discriminating feigned from genuine psychopathology (ds > .90). For feigned cognitive impairment, the FBS-r produced very large effect sizes with feigned TBI (M d = 1.41); however, its cut scores were more indicative of general feigning than feigned cognitive impairment. Finally, Fs yielded a large effect size (d = 1.23) for feigned medical complaints, but its cut scores were more likely to identify examinees feigning mental disorders (M sensitivity = .74) than medical complaints (M sensitivity = .43). These findings are discussed within the context of clinical forensic evaluations.     

Assessment of Emotional Avoidance in Adolescents: Psychometric Properties of a New Multidimensional Measure

Emotional avoidance—which includes cognitive and attentional processes that function as means of avoiding or dampening emotional experiences—may be a transdiagnostic risk and maintenance factor for emotional disorders. However, existing measures generally assess separate aspects of emotional avoidance, and few multidimensional measures exist for adolescents. The aim of the current study was to establish the psychometric properties of a new multidimensional measure of emotional avoidance for adolescents--the Emotional Avoidance Strategy Inventory for Adolescents (EASI-A; Fairholme et al. 2008)--employing an exploratory structural equation modeling framework. Analyses yielded a three-factor structure for the EASI-A, including subscales measuring Avoidance of Emotion Expression, Avoidance of Thoughts and Feelings, and Distraction. Moderate correlations were observed between the EASI-A and a measure of thought suppression, and the EASI-A was significantly associated with anxiety and depression symptoms. The EASI-A is a new, psychometrically sound measure that will aid in the assessment of avoidance as a vulnerability factor for psychopathology and as an outcome and mechanism for treatments of emotional disorders in adolescents.     

Extended Mechanistic Explanations: Expanding the Current Mechanistic Conception to Include More Complex Biological Systems

Mechanistic accounts of explanation have recently found popularity within philosophy of science. Presently, we introduce the idea of an extended mechanistic explanation, which makes explicit room for the role of environment in explanation. After delineating Craver and Bechtel’s (2007) account, we argue this suggestion is not sufficiently robust when we take seriously the mechanistic environment and modeling practices involved in studying contemporary complex biological systems. Our goal is to extend the already profitable mechanistic picture by pointing out the importance of the mechanistic environment. It is our belief that extended mechanistic explanations, or mechanisms that take into consideration the temporal sequencing of the interplay between the mechanism and the environment, allow for mechanistic explanations regarding a broader group of scientific phenomena.
