Individual differences in the perception of similarity and difference

Thematically related concepts like coffee and milk are judged to be more similar than thematically unrelated concepts like coffee and lemonade. We investigated whether thematic relations exert a small effect that occurs consistently across participants (i.e., a generalized model), or a large effect that occurs inconsistently across participants (i.e., an individualized model). We also examined whether difference judgments mirrored similarity or whether these judgments were, in fact, non-inverse. Five studies demonstrated the necessity of an individualized model for both perceived similarity and difference, and additionally provided evidence that thematic relations affect similarity more than difference. Results suggest that models of similarity and difference must be attuned to large and consistent individual variability in the weighting of thematic relations.     

The role of gratitude in the development of social support, stress, and depression: Two longitudinal studies

In two longitudinal studies, the authors examined the direction of the relationships between trait gratitude, perceived social support, stress, and depression during a life transition. Both studies used a full cross-lagged panel design, with participants completing all measures at the start and end of their first semester at college. Structural equation modeling was used to compare models of direct, reverse, and reciprocal models of directionality. Both studies supported a direct model whereby gratitude led to higher levels of perceived social support, and lower levels of stress and depression. In contrast, no variable led to gratitude, and most models of mediation were discounted. Study 2 additionally showed that gratitude leads to the other variables independently of the Big Five factors of personality. Overall gratitude seems to directly foster social support, and to protect people from stress and depression, which has implications for clinical interventions.     

Overconfidence at the Keyboard: Confidence and Accuracy in Interpreting Affect in E‐Mail Exchanges

Gesture, voice, expression, and context add richness to communications that increase chances of accurate interpretation. E‐mails lack much of this richness, leading readers to impose their own richness. Three experiments tested the effect of communicator relationship and availability of context on e‐mail writer and reader confidence levels and accuracy. Effects of nonverbal and verbal behavior were also investigated. Results showed that confidence levels for both writers and readers were high, yet somewhat unwarranted based on accuracy rates. Further, writers had more confidence that friends would correctly interpret e‐mails than strangers, although friends showed no more accuracy. Findings suggest that reliance upon friendship and context, as well as verbal and nonverbal cues, to interpret emotion in e‐mail is ineffective, sometimes detrimental.     

Is a Pink Cow Still a Cow? Individual Differences in Toddlers' Vocabulary Knowledge and Lexical Representations

When a toddler knows a word, what does she actually know? Many categories have multiple relevant properties; for example, shape and color are relevant to membership in the category banana . How do toddlers prioritize these properties when recognizing familiar words, and are there systematic differences among children? In this study, toddlers viewed pairs of objects associated with prototypical colors. On some trials, objects were typically colored (e.g., Holstein cow and pink pig); on other trials, colors were switched (e.g., pink cow and Holstein‐patterned pig). On each trial, toddlers were directed to find a target object. Overall, recognition was disrupted when colors were switched, as measured by eye movements. Moreover, individual differences in vocabularies predicted recognition differences: Toddlers who say fewer shape‐based words were more disrupted by color switches. “Knowing” a word may not mean the same thing for all toddlers; different toddlers prioritize different facets of familiar objects in their lexical representations.     

A deafening flash! Visual interference of auditory signal detection

In some people, visual stimulation evokes auditory sensations. How prevalent and how perceptually real is this? 22% of our neurotypical adult participants responded ‘Yes' when asked whether they heard faint sounds accompanying flash stimuli, and showed significantly better ability to discriminate visual ‘Morse-code’ sequences. This benefit might arise from an ability to recode visual signals as sounds, thus taking advantage of superior temporal acuity of audition. In support of this, those who showed better visual relative to auditory sequence discrimination also had poorer auditory detection in the presence of uninformative visual flashes, though this was independent of awareness of visually-evoked sounds. Thus a visually-evoked auditory representation may occur subliminally and disrupt detection of real auditory signals. The frequent natural correlation between visual and auditory stimuli might explain the surprising prevalence of this phenomenon. Overall, our results suggest that learned correspondences between strongly correlated modalities may provide a precursor for some synaesthetic abilities.     

Expectation creates something out of nothing: The role of attention in iconic memory reconsidered

Conscious experience is modulated by attention and expectation, yet is believed to be independent of attention. The experiments on iconic memory (IM) are usually taken as support for this claim. However, a recent experiment demonstrated that when attention is diverted away from the IM letter display subjects fail to see the absence of IM letters. Here we contribute to the ongoing debate by overcoming experimental shortcomings of this previous experiment, by measuring subjective visibility and by testing the effect of the post-cue. We were able to replicate these earlier findings and extend them by demonstrating that subjects who do not realize the absence of letters perceive illusory letters. This result means that there is still phenomenal consciousness, even when attention is diverted. Expectation creates illusory content that overwrites valid IM content. Taken together these findings suggest that the present experimental paradigm is not appropriate to make claims about IM content.

Integrative problem-centered metaframeworks therapy II: planning, conversing, and reading feedback

This is the second of 2 articles presenting Integrative Problem Centered Metaframeworks (IPCM) Therapy, a multisystemic, integrative, empirically informed, and common factor perspective for family, couple, and individual psychotherapy. The first article presented IPCM's foundation concepts and Blueprint for therapy, focusing on the first Blueprint component—Hypothesizing or assessment. This article, focusing on intervention, presents the other 3 Blueprint components—Planning, Conversing, and Feedback. Articulated through the Blueprint, intervention is a clinical experimental process in which therapists formulate hypotheses about the set of constraints (the Web) within a client system that prevents problem resolution, develop a therapeutic Plan based on those hypotheses, implement the Plan through a coconstructed dialogue with the clients, and then evaluate the results. If the intervention is not successful, the results become feedback to modify the Web, revise the Plan, and intervene again. Guided by the therapeutic alliance, this process repeats until the presenting problems resolve. IPCM Planning sequentially integrates the major empirically and yet‐to‐be empirically validated therapies and organizes their key strategies and techniques as common factors. Conversing and Feedback employ empirical STIC^® (Systemic Therapy Inventory of Change) data collaboratively with clients to formulate hypotheses and evaluate interventions. This article emphasizes the art and science of IPCM practice.     

Personality and gang embeddedness

Gang membership can be transient or persistent, and most persons who participate in such groups at one point in their lives grow out of the lifestyle. The personality dynamics driving gang membership are poorly understood, although the five-factor model of personality has proved an effective way to understanding many types of antisocial behaviour. Using dichotomous self-nomination 152 remand and sentenced participants incarcerated within a general prison in London, UK indicated their gang embeddedness as youths, prior to custody, within prison, and as an intent following release. This enabled behavioural intention to be incorporated into the model as well as historical factors. Constructs derived from a variety of personality measures and constructs were used to predict overall reported gang embeddedness. These predictors reduced to two underlying dimensions: personal resilience and antisocial personality. Path analysis showed the antisocial personality dimension predicted previous convictions and degree of gang embeddedness, whereas resilience did not. The direct and indirect effects of the composite antisocial personality dimension explained 50% of the overall observed variance in gang embeddedness. We suggest that gang membership may reflect normal assortative processes within the members of such groups.     

Individual differences in spatial relation processing: effects of strategy, ability, and gender

Numerous studies have focused on the distinction between categorical and coordinate spatial relations. Categorical relations are propositional and abstract, and often related to a left hemisphere advantage. Coordinate relations specify the metric information of the relative locations of objects, and can be linked to right hemisphere processing. Yet, not all studies have reported such a clear double dissociation; in particular the categorical left hemisphere advantage is not always reported. In the current study we investigated whether verbal and spatial strategies, verbal and spatial cognitive abilities, and gender could account for the discrepancies observed in hemispheric lateralization of spatial relations. Seventy-five participants performed two visual half field, match-to-sample tasks (Van der Ham, van Wezel, Oleksiak, & Postma, 2007; Van der Ham, Raemaekers, van Wezel, Oleksiak, and Postma, 2009) to study the lateralization of categorical and coordinate relation processing. For each participant we determined the strategy they used in each of the two tasks. Consistent with previous findings, we found an overall categorical left hemisphere advantage and coordinate right hemisphere advantage. The lateralization pattern was affected selectively by the degree to which participants used a spatial strategy and by none of the other variables (i.e., verbal strategy, cognitive abilities, and gender). Critically, the categorical left hemisphere advantage was observed only for participants that relied strongly on a spatial strategy. This result is another piece of evidence that categorical spatial relation processing relies on spatial and not verbal processes.
