Covert shifts of attention can account for the functional role of “eye movements to nothing”

When trying to remember verbal information from memory, people look at spatial locations that have been associated with visual stimuli during encoding, even when the visual stimuli are no longer present. It has been shown that such “eye movements to nothing” can influence retrieval performance for verbal information, but the mechanism underlying this functional relationship is unclear. More precisely, covert in comparison to overt shifts of attention could be sufficient to elicit the observed differences in retrieval performance. To test if covert shifts of attention explain the functional role of the looking-at-nothing phenomenon, we asked participants to remember verbal information that had been associated with a spatial location during an encoding phase. Additionally, during the retrieval phase, all participants solved an unrelated visual tracking task that appeared in either an associated (congruent) or an incongruent spatial location. Half the participants were instructed to look at the tracking task, half to shift their attention covertly (while keeping the eyes fixed). In two experiments, we found that memory retrieval depended on the location to which participants shifted their attention covertly. Thus, covert shifts of attention seem to be sufficient to cause differences in retrieval performance. The results extend the literature on the relationship between visuospatial attention, eye movements, and verbal memory retrieval and provide deep insights into the nature of the looking-at-nothing phenomenon.     

Do Smarter People Employ Better Decision Strategies? The Influence of Intelligence on Adaptive Use of the Recognition Heuristic

Within the adaptive toolbox approach, it has repeatedly been shown that, on average, people tend to adapt their decision strategies to the decision context. Building upon these results, we investigated whether individuals systematically differ in their ability to successfully adapt to the situation when applying the fast‐and‐frugal recognition heuristic (RH). In decisions between recognized and unrecognized choice objects, individuals can base their choices solely on recognition, as predicted by the RH, or they can use further knowledge retrieved from memory. Since intelligence has been conceived as the ability to successfully adapt to different situations, we expected intelligence to influence the degree of adaptive use of the RH. To test this hypothesis, we first re‐analyzed data that referred to a decision domain for which RH‐use is known to perform well. As expected, individual RH‐use increased with general intelligence. Next, we designed an experiment addressing individual RH‐use in two new decision domains, one domain for which RH‐use was less effective than knowledge‐use and another domain for which both strategies were about equally effective. In addition, we tested whether fluid or crystallized intelligence best predicts adaptive use of the RH. RH‐use was found to decrease with fluid but not crystallized intelligence when RH‐use was less effective than use of further knowledge. In contrast, there was no significant association between either type of intelligence and RH‐use when none of the two strategies was optimal. We conclude that adaptive use versus non‐use of the RH is moderated by fluid intelligence. Copyright © 2017 John Wiley & Sons, Ltd.     

A Note on the Power of Multiattribute One‐switch Utility Functions

One‐switch utility functions model situations in which the preference between two alternatives switches only once as the outcome of one attribute of both alternatives changes from low to high. Recent research cites evidence that the sum of exponential functions (sumex) is the most convincing type for modelling one‐switch utility functions. Sumex functions allow to model exactly one preferential switch and they are convenient for estimating one‐switch utility functions. However, it is unclear so far if sumex functions are suitable to model preferential switches that are perceivable by a decision maker. This paper first analyses how different the utility of two alternatives before and after a preferential can be modelled with sumex functions given that the preferential switch is caused by a particular attribute outcome improvement. It thereafter investigates how accurately decision makers perceive such utility differences. Copyright © 2015 John Wiley & Sons, Ltd.     

Smoking is ok as long as I eat healthily: Compensatory Health Beliefs and their role for intentions and smoking within the Health Action Process Approach

Compensatory Health Beliefs (CHBs) are defined as beliefs that the negative consequences of unhealthy behaviours can be compensated for by engaging in healthy behaviours. CHBs have not yet been investigated within a framework of a behaviour change model, nor have they been investigated in detail regarding smoking. Thus, the aim of this study was to investigate on a theoretical basis whether smoking-specific CHBs, as a cognitive construct, add especially to the prediction of intention formation but also to changes in smoking behaviour over and above predictors specified by the Health Action Process Approach (HAPA). The sample comprised 385 adolescent smokers (mean age: 17.80). All HAPA-specific variables and a smoking-specific CHB scale were assessed twice, 4 months apart. Data were analysed using structural equation modelling. Smoking-specific CHBs were significantly negatively related to the intention to stop smoking over and above HAPA-specific predictors. Overall, 39% of variance in the intention to quit smoking was explained. For the prediction of smoking, CHBs were not able to explain variance over and above planning and self-efficacy. Thus, smoking-specific CHBs seem mainly important in predicting intentions but not behaviour. Overall, the findings contribute to the understanding of the role of smoking-specific CHBs within a health-behaviour change model.     

Changes in self-regulatory cognitions as predictors of changes in smoking and nutrition behaviour

Most longitudinal, correlational studies on health-behaviour change examine effects of Time1 social-cognitive predictors on subsequent behaviour. In contrast, our research focusses on associations between changes in predictors with change in behaviour. The Health Action Process Approach (HAPA) distinguishes between motivational predictors for intention formation and volitional predictors for behavioural change and served as theoretical basis. Two online-studies were launched targeting different behaviours (low-fat diet, smoking), different samples (Study 1: N = 469; Study 2: N = 441) and different time spans (Study 1: 3 months, Study 2: 4 weeks). Data were analysed by means of structural equation modelling with latent difference scores. Both studies resulted in almost parallel prediction patterns. Change in risk awareness and change in outcome expectancies did not result in change in intentions, whereas change in self-efficacy was of crucial importance. Change in behaviour was associated with change in action planning and action control over and above the effects of intentions. In one study, increases in self-efficacy yielded increases in behaviour change. Results demonstrate that change in action planning and especially action control was of great importance for behaviour change across two different behaviours. Analysing change in social-cognitive predictors allows drawing precise conclusions for interventions.     

From enjoyment to physical activity or from physical activity to enjoyment? Longitudinal associations in parent–child dyads

Abstract

Background: This longitudinal dyadic study used cross-lagged analyses to examine reciprocal patterns of associations between physical activity (PA) enjoyment and moderate-to-vigorous PA (MVPA) among children and their parents.

Methods: At Time 1 (T1) 879 parent–child dyads provided their data. The follow-up (Time 2, T2) took place 7–8-months later. MVPA and PA enjoyment scales were filled out separately by parents and children at T1 and T2.

Findings: Child PA enjoyment (T1) predicted a higher level of child MVPA (T2), parental PA enjoyment (T1) explained a higher level of parental MVPA (T2), and parental MVPA (T1) predicted a higher level of parental PA enjoyment (T2). Furthermore, child PA enjoyment (T1) predicted a higher level of parental PA enjoyment (T2).

Conclusions: Child PA enjoyment was the key variable predicting child and parental outcomes. In particular, it explained child MVPA, but also PA enjoyment among parents.     

In-Group Favoritism in International Justice Concerns: Power,Involvement, and Attitudes toward the Iraq War and the Cross Straits Relationship in Five Societies

Surveys in the USA, New Zealand, Taiwan, Japan, and China examined attitudes toward the Iraq War and the Cross-Straits Relationship between China and Taiwan. Factor analyses revealed a four-factor solution of justice concerns: (a) national mandate for military intervention, (b) international mandate against military action, (c) procedural justice, and (d) distributive justice issues. Americans and mainland Chinese were significantly different in an in-group favoring direction compared to other societies regarding justice concerns involving their nation. Taiwan, the low-powered society in the Cross-Straits Relationship, was like the uninvolved societies. Justice in international relations is filtered through in-group favoritism for powerful states.     

The face of fluency: Semantic coherence automatically elicits a specific pattern of facial muscle reactions

This study shows that high conceptual fluency induced by hidden semantic coherence automatically triggers a specific pattern of facial expressions. In the present study, word triads that either had or had not a common remote associate were read by individuals while automatic facial responses were recorded. Although participants were ignorant about the underlying semantic structure, participants’ faces showed an activation of the smiling muscle zygomaticus major (indicating increased positive affect), a relaxation of the frowning muscle corrugator supercilii (indicating decreased negative affect and mental effort), and a relaxation of the forehead muscle frontalis (indicating increased familiarity) after reading coherent compared to incoherent word triads. Implications for intuitive judgements of semantic coherence are discussed.     

Dreams are more negative than real life: Implications for the function of dreaming

Dream content studies have revealed that dream experiences are negatively biased; negative dream contents are more frequent than corresponding positive dream contents. It is unclear, however, whether the bias is real or due to biased sampling, i.e., selective memory for intense negative emotions. The threat simulation theory (TST) claims that the negativity bias is real and reflects the evolved biological function of dreaming. In the present study, we tested the hypothesis of the TST that threatening events are overrepresented in dreams, i.e., more frequent and more severe in dreams than in real life. To control for biased sampling, we used as a baseline the corresponding negative events in real life rather than the corresponding positive events in dreams. We collected dream reports (N=419) and daily event logs (N=490) from 39 university students during a two-week period, and interviewed them about real threat experiences retrievable from autobiographical memory (N=714). Threat experiences proved to be much more frequent and severe in dreams than in real life, and Current Dream Threats more closely resembled Past than Current Real Threats. We conclude that the TST's predictions hold, and that the negativity bias is real.     

Sex‐specific Differential Prediction of Academic Achievement by German Ability Tests

Tests of cognitive ability play a major role in the selection of students. Still, data regarding the fairness of standardized tests in Germany is scarce. We use three samples (N = 2,616; 58% women) from German universities to investigate the sex‐specific differential prediction of college performance based on intelligence tests. The predictive bias we find is small and in line with US‐American research. The direction of the effect depends on the cognitive ability domain investigated: Numeric test scores are prone to disadvantage women whereas verbal test scores are more likely to discriminate against men. Including high school grade point average in the prediction model can help to offset differential prediction that underestimates women's academic achievement.
