Generalisation of fear and avoidance along a semantic continuum

Directly conditioned fear and avoidance readily generalises to dissimilar but conceptually related stimuli. Here, for the first time, we examined the conceptual/semantic generalisation of both fear and avoidance using real words (synonyms). Participants were first exposed to a differential fear conditioning procedure in which one word (e.g., “broth”; CS+) was followed with brief electric shock [unconditioned stimulus (US)] and another was not (e.g., “assist”; CS–). Next, an instrumental conditioning phase taught avoidance in the presence the CS+ but not the CS–. During generalisation testing, synonyms of the CS+ (e.g., “soup”; GCS+) and CS– (e.g., “help”; GCS–) were presented in the absence of shock. Conditioned fear and avoidance, measured via skin conductance responses, behavioural avoidance and US expectancy ratings, generalised to the semantically related, but not to the semantically unrelated, synonyms. Findings have implications for how natural language categories and concepts mediate the expansion of fear and avoidance repertoires in clinical contexts.     

Toward an Understanding of Religious Tolerance: Quest Religiousness and Positive Attitudes Toward Religiously Dissimilar Others

We interact frequently with individuals with religious beliefs that vary from our own. Although we may naturally prefer interacting with religiously similar others, individuals vary in their attitudes toward religiously dissimilar others. In the present set of studies, we examined how variability in quest religiousness affects religious tolerance. In Study 1 (N = 159), we found that quest religiousness in Christian undergraduates was associated with positive attitudes toward both non-Christian religious groups and atheists. In Study 2, 118 Christian undergraduates evaluated vignettes regarding a devout moral or an average morality Christian (ingroup) or Muslim (outgroup). Participants preferred moral targets relative to less moral targets. However, when rating moral targets, participants high in quest religiousness preferred the Muslim target (religious outgroup member), whereas those low in quest religiousness preferred the Christian target (religious ingroup member). We discuss implications for the links between quest religiousness and religious tolerance.     

Reduced specificity and enhanced subjective experience of future thinking in ageing: the influence of avoidance and emotion-regulation strategies

Future thinking in older adults is characterised by a lack of specificity of imagined events and by an equal or even higher subjective experience, compared to younger adults. We considered whether this lack of specificity stemmed partly from the avoidance of a somewhat disturbing future and then examined the extent to which certain types of emotion-regulation strategies, namely positive reappraisal and positive refocusing, contributed to the subjective experience of future thinking. Middle-aged and older adults completed an adapted version of the AMT, in which temporal distance and cue word valence were manipulated, thus resulting in future conditions assumed to represent varying degrees of discomfort. Results indicate that distant future and negative cues restricted both the specificity and the subjective experience of future thinking. In addition, the use of avoidance strategies predicted the nature of future thoughts in the context of a supposed uncomfortable future (i.e., a distant future induced by negative cues), although it followed quite different age-related patterns. Together with the findings that positive reappraisal and positive refocusing (to a lesser extent) contributed to the subjective experience of future thinking, this study indicates that how individuals imagine their personal future also relies on affect- and emotion-regulation strategies.     

When Happiness is Both Joy and Purpose: The Complexity of the Pursuit of Happiness and Well-Being is Related to Actual Well-Being

Journal of Happiness Studies - People differ in how they define and pursue happiness and well-being (HWB). Previous studies suggested that the best way to achieve a high level of well-being might...     

Unconscious semantic activation depends on feature-specific attention allocation

We examined whether semantic activation by subliminally presented stimuli is dependent upon the extent to which participants assign attention to specific semantic stimulus features and stimulus dimensions. Participants pronounced visible target words that were preceded by briefly presented, masked prime words. Both affective and non-affective semantic congruence of the prime-target pairs were manipulated under conditions that either promoted selective attention for affective stimulus information or selective attention for non-affective semantic stimulus information. In line with our predictions, results showed that affective congruence had a clear impact on word pronunciation latencies only if participants were encouraged to assign attention to the affective stimulus dimension. In contrast, non-affective semantic relatedness of the prime-target pairs produced no priming at all. Our findings are consistent with the hypothesis that unconscious activation of (affective) semantic information is modulated by feature-specific attention allocation.     

Her own decision: impairment and authenticity in adolescence

This case describes an adolescent in a crisis of a chronic medical condition whose situation is complicated by substance abuse and mental illness. D. Micah Hester provides an analytic approach, teasing apart the multiple layers of medical, developmental, and moral issues at hand and describing possible responses and outcomes. Amy T. Campbell examines existing legal guidelines for adolescent decision making, arguing that greater space exists for clinical discretion in these matters than commonly thought. Cheryl D. Lew discusses the development of agency in adolescent patients, the ideal of autonomous decision making in the context of impairment and chronic illness, and the obligation of healthcare teams to examine an adolescent patient's decisions in relation to her identity.     

Norepinephrine-mediated emotional arousal facilitates subsequent pattern separation

Pattern separation, the process by which similar experiences can be stored as distinct memories, has been ascribed to the dentate gyrus (DG) of the hippocampus. The DG is the target of noradrenergic modulation directly and indirectly via the basolateral amygdala. We tested the hypothesis that noradrenergic activation (tested using salivary alpha-amylase) potentiates DG function, enhancing pattern separation, by showing participants fearful stimuli in a pre-training task and then testing their capacity for pattern separation in a later test. Consistent with our hypothesis, we found that increased levels of salivary alpha-amylase were positively correlated with enhanced pattern separation performance even after accounting for general enhancements in recognition.     

The eACS: Attentional control in the presence of emotion

We present a questionnaire – The Emotional Attentional Control Scale (eACS) – An adaptation of the original Attentional Control Scale (ACS) that assesses the voluntary control of attention. A low score on the ACS has been associated with high levels of anxiety and depression. As the ACS items are affectively neutral, some people scoring high on the ACS may still show low levels of attentional control (AC) in more emotionally-demanding situations. We propose that the eACS, which focuses on the emotional modulation of AC, may explain additional variance in AC deficits associated with psychopathology.     

Associations between components of rumination and autobiographical memory specificity as measured by a Minimal Instructions Autobiographical Memory Test

Clinical studies have shown that rumination functions as a mediator between overgeneral memory—the tendency to retrieve autobiographical memories in a non-specific format—and depression. Recently, rumination has been dismantled into two distinct subcomponents: reflection, which is more adaptive, and brooding, which is more maladaptive. In the present study we examined the differential relationships of these two rumination subcomponents with autobiographical memory specificity and their mediational role for the relationship between reduced memory specificity and depression in a non-clinical sample. In addition, we investigated the usefulness of a “minimal instructions” version of the Autobiographical Memory Test (AMT) to measure memory specificity in non-clinical populations. Results indicated that the use of minimal instructions can increase the AMT's sensitivity to detect reduced autobiographical memory specificity in non-clinical individuals. Further it was found that brooding, and not reflection, is significantly associated with reduced autobiographical memory specificity and functions as a mediator between reduced memory specificity and depression.
