Video reviews

The Journal of Family Therapy intends to publish reviews of teaching videos regularly. Anyone wishing to submit videos for review is invited to contact the video reviews editor. Videos are expensive to produce. Their purchase price reflects this, and, where possible, it is recommended to readers that they sample by hiring before buying.     

Reality exists O.K.? An argument against constructivism and social constructionism

This paper reviews the way in which realism and constructivism have implicitly and explicitly underlain assumptions made by people in the helping professions about what can be known. Constructivism and the more recently rediscovered social constructionism have been appropriately influential in what is counted as knowledge in family therapy, but it is argued that they have gone too far in their assumption that a structured reality makes no contribution to what can be known. An alternative position is advocated, one which takes into account a relationship between the knower and the known. Some of the implications of such a co-constructivist position for family therapy are outlined.     

Threshold nonlinearities and signal detection theory

The review summarizes Kulikowski's contributions to the mechanisms involved in visual detection and discrimination. His findings provide strong evidence for the existence of 'barriers' which block weak activity in the visual system. It is proposed that the properties of these barriers may underlie near-optimal detection in conditions of signal uncertainty.     

Extraversion and job performance: How context relevance and bandwidth specificity create a non-linear,positive, and asymptotic relationship

The personality factor of extraversion has been associated with performance in some occupations (e.g., sales), and it has been one of the most consistent personality predictors of leadership. Recent research indicates that extraversion could have a non-linear relation with performance. At the same time, many researchers have contended that scholars should utilize measures of personality narrower than factors and that the bandwidth and relevance of personality should fit both the criterion and the context of a study. We argue and find that by examining an aspect of extraversion (i.e., social potency) in a particular vocational context (i.e., enterprising job demands), non-linear, asymptotic (diminishing marginal benefits) effects will be demonstrated on a relevant type of performance (i.e., enterprising job performance). We review implications, limitations, and avenues for future research.

Unbelievable?! Theistic/Epistemological Viewpoint Affects Religion–Health Relationship

Research suggests that Religion/Spirituality promotes a variety of positive health outcomes. However, despite reporting lower levels of Religion/Spirituality, non-believers report comparable levels of health to believers. The current study tested the hypothesis that Religion/Spirituality does not have a uniform effect on health for all persons, and tested theological/epistemological categories as moderators. Using the 2012 and 2014 General Social Survey (N = 2670), the relationship between Religion/Spirituality and happiness and self-rated health was investigated. Results indicated that Gnostic Theists experienced Religion/Spirituality more positively than their peers did; Agnostic Theists experienced Religion/Spirituality less positively than their peers did; and Negative Atheists experienced Religion/Spirituality less positively than their peers did. These findings suggested that Religion/Spirituality is not associated with salutary effects for all persons, and that whether a person believes in god(s) and how confident he/she was in god(s)’ existence, influenced his/her experience with Religion/Spirituality.     

Expertise Shapes Multimodal Imagery for Wine

Although taste and smell seem hard to imagine, some people nevertheless report vivid imagery in these sensory modalities. We investigate whether experts are better able to imagine smells and tastes because they have learned the ability, or whether they are better imaginers in the first place, and so become experts. To test this, we first compared a group of wine experts to yoked novices using a battery of questionnaires. We show for the first time that experts report greater vividness of wine imagery, with no difference in vividness across sensory modalities. In contrast, novices had more vivid color imagery than taste or odor imagery for wines. Experts and novices did not differ on other vividness of imagery measures, suggesting a domain-specific effect of expertise. Critically, in a second study, we followed a group of students commencing a wine course and a group of matched control participants. Students and controls did not differ before the course, but after the wine course students reported more vivid wine imagery. We provide evidence that expertise improves imagery, exemplifying the extent of plasticity of cognition underlying the chemical senses.
