Being of two minds: Switching mindsets exhausts self-regulatory resources

The human psyche is equipped with the capacity to solve problems using different mental states or mindsets. Different mindsets can lead to different judgment and decision making styles, each associated with its own perspective and biases. To change perspective, people can, and often do, switch mindsets. We argue, however, that mindset switching can be costly for subsequent decisions. We propose that mindset switching is an executive function that relies on the same psychological resource that governs other acts of executive functioning, including self-regulation. This implies that there are psychic costs to switching mindsets that are borne out in depleted executive resources. One implication of this framework is that switching mindsets should render people more likely to fail at subsequent self-regulation than they would if maintaining a consistent mindset. The findings from experiments that manipulated mindset switching in five domains support this model.     

Differential effects of reasoning and speed training in children

The goal of this study was to determine whether intensive training can ameliorate cognitive skills in children. Children aged 7 to 9 from low socioeconomic backgrounds participated in one of two cognitive training programs for 60 minutes/day and 2 days/week, for a total of 8 weeks. Both training programs consisted of commercially available computerized and non-computerized games. Reasoning training emphasized planning and relational integration; speed training emphasized rapid visual detection and rapid motor responses. Standard assessments of reasoning ability - the Test of Non-Verbal Intelligence (TONI-3) and cognitive speed (Coding B from WISC IV) - were administered to all children before and after training. Neither group was exposed to these standardized tests during training. Children in the reasoning group improved substantially on TONI (Cohen's d = 1.51), exhibiting an average increase of 10 points in Performance IQ, but did not improve on Coding. By contrast, children in the speed group improved substantially on Coding (d = 1.15), but did not improve on TONI. Counter to widespread belief, these results indicate that both fluid reasoning and processing speed are modifiable by training.     

Using Sexual Appeals in Advertising to Sell Cosmetic Surgery: A Content Analysis from 1986 to 2007

This study provides an account of how sexual appeals are used to promote cosmetic surgery. A content analysis of advertisements appearing between 1986 and 2007 in large city magazines reveals that advertisements position surgery as a means of boosting sex-esteem, and enhancing one’s sexual attractiveness, a pattern different from that of branded consumer products and services. Invasive procedures such as liposuction and breast augmentation are the top procedures advertised with sexual appeals and most advertisements feature nude or partially-nude white female models. The findings help expand knowledge about cosmetic surgery advertising, how sex is used to sell an ideal beauty standard attainable through invasive medical services, and the use of sexual content in a new context, that of medical-related advertising for cosmetic surgery.     

An experimental approach towards the evaluation of a seat belt campaign with an inside view on the psychology behind seat belt use

A Belgian national safety belt campaign was evaluated by means of a questionnaire survey in an adolescent sample. The evaluation was done through a three group after-only design with the use of one control group and two experimental groups. The first experimental group, the attentive group, was exposed to the campaign material in a very direct, attentive way, whereas the second experimental group, the pre-attentive group, was exposed rather inattentively. The framework of the Theory of Planned Behaviour (TPB) was applied and extended with a habit and a past behaviour variable in order to verify whether seat belt usage is to be understood as an automaticity mechanism (i.e., habitual or repeated past behaviour) or as planned behaviour. In terms of campaign effect, the comparison of the pre-attentive group and the control group revealed no significant differences. However, the attentive group and the control group differed significantly regarding two basic dimensions of perceived behavioural control (i.e., confidence and motivation), habit, past behaviour, behavioural intention and behaviour. In terms of explaining seat belt usage, linear regression models were fitted and gave most support for the repeated past behaviour approach. According to the latter, using seat belts is recycling an originally reasoned behaviour, yet without systematically going through the whole underlying reasoning every time a situation in which the decision to wear a seat belt (or not) presents itself. The practical implications of these findings are discussed more in detail.     

The Limits of Principlism and Recourse to Theory: The Example of Telecare

Principlism is the approach promoted by Beauchamp and Childress for addressing the ethics of medical practice. Instead of evaluating clinical decisions by means of full-scale theories from moral philosophy, Beauchamp and Childress refer people to four principles—of autonomy, beneficence, nonmaleficence, and justice. Now it is one thing for principlism to be invoked in an academic literature dwelling on a stock topic of medical ethical writing: end-of-life decisions, for example. It is another when the topic lies further from the mainstream. In such cases the cost of reaching for the familiar Beauchamp and Childress framework, with its formulaic set of concerns, may be to miss something morally important. After discussing an example of the sort of academic literature I have in mind, I propose to distinguish the uses of the formulaic from the uses of the more unapologetically theoretical in applied ethics, and to suggest that the latter can make up for some of the limitations of the former. This is not to say that the more theoretical literature has no limitations of its own, or that it should take the place of the formulaic. On the contrary, there is room in applied ethics and a use in applied ethics for both. But there is a sense in which there is a greater dependence of principlism on theory than the other way round, and at the end I try to spell out the significance of this fact.     

Come rain or come shine: individual differences in how weather affects mood

There is a widespread belief that weather affects mood. However, few studies have investigated this link, and even less is known about individual differences in people's responses to the weather. In the current study, we sought to identify weather reactivity types by linking self-reported daily mood across 30 days with objective weather data. We identified four distinct types among 497 adolescents and replicated these types among their mothers. The types were labeled Summer Lovers (better mood with warmer and sunnier weather), Unaffected (weak associations between weather and mood), Summer Haters (worse mood with warmer and sunnier weather), and Rain Haters (particularly bad mood on rainy days). In addition, intergenerational concordance effects were found for two of these types, suggesting that weather reactivity may run in the family. Overall, the large individual differences in how people's moods were affected by weather reconciles the discrepancy between the generally held beliefs that weather has a substantive effect on mood and findings from previous research indicating that effects of weather on mood are limited or absent.

Unconscious task application

The nature of unconscious information processing is a heavily debated issue in cognitive science (e.g., Kouider & Dehaene, 2007), and neuroscience (e.g., Crick & Koch, 1998). Traditionally, it has been thought that unconscious cognitive processing is restricted to knowledge that is strongly prepared by conscious processes (e.g., Dehaene et al., 1998). In three experiments, we show that the task that is performed consciously can also be applied unconsciously to items outside the current task set. We found that a same–different judgment of two target stimuli was also performed on two subliminally presented prime stimuli. This was true for target and prime stimuli from entirely different categories, as well as for prime and target stimuli at different levels of abstraction. These results reveal that unconscious processing can generalize more widely than previously accepted.     

Counterconditioning reduces cue-induced craving and actual cue-elicited consumption

Cue-induced craving is not easily reduced by an extinction or exposure procedure and may constitute an important route toward relapse in addictive behavior after treatment. In the present study, we investigated the effectiveness of counterconditioning as an alternative procedure to reduce cue-induced craving, in a nonclinical population. We found that a cue, initially paired with chocolate consumption, did not cease to elicit craving for chocolate after extinction (repeated presentation of the cue without chocolate consumption), but did so after counterconditioning (repeated pairing of the cue with consumption of a highly disliked liquid, Polysorbate 20). This effect persisted after 1 week. Counterconditioning moreover was more effective than extinction in disrupting reported expectancy to get to eat chocolate, and also appeared to be more effective in reducing actual cue-elicited chocolate consumption. These results suggest that counterconditioning may be more promising than cue exposure for the prevention of relapse in addictive behavior.     

A short self-report measure of problems with executive function suitable for administration via the Internet

This article describes a short self-report measure of problems with executive function designed for use in Internet-mediated research. In Study 1, participants completed the online measure (Webexec) using a browser but under laboratory conditions. They also completed a paper self-report measure of executive problems (the Dysexecutive Questionnaire; DEX) and three objective tasks involving executive function: reverse digit span, semantic fluency (unconstrained), and semantic fluency (constrained). Webexec scores correlated positively with the DEX and negatively with the three executive tasks. Further evidence of construct validity came from Study 2, in which Webexec scores correlated positively with both use of cannabis and prospective memory problems reported in an online drug questionnaire. Webexec thus appears suitable for online research with normal populations.
