Effects on Episodic Memory of Stimulus Richness, Intention to Learn, and Extra-Study Repetition: Similar Profiles Across the Adult Life Span

The ability to benefit from various kinds of cognitive support in episodic memory was studied in a population-based sample of healthy adults aged 35–80 years (N = 1,000). The participants studied pictures of faces and names of 10-year-old children with instructions to remember the faces and the surnames. After study, an implicit name stem-completion test was administered, followed by face- and name-recognition tests. There was a negative age effect across all task variables. Across age, recognition was higher for faces than for names. An age-invariant positive effect of intention to learn was observed. Also, name completion and recognition performance showed a positive relationship across the adult life span. Overall, the results are in agreement with the views that (a) age-related episodic memory deficits are highly generalizable and (b) effects of cognitive support on memory are typically of equal size across the adult life span.     

Cognitive consequences of motivational orientation: perceived similarity between objects

Recent findings suggest that the unconscious activation of the motivational orientations of approach and avoidance is accompanied by the adoption of a more global and a more local processing style, respectively. A global processing style, in turn, is assumed to instigate a focus on similarities whereas a local processing style is assumed to instigate a focus on differences. Integrating these two ideas, the present research examines the hypothesis that participants under approach perceive objects as more similar to each other than participants under avoidance. To test this assumption, we induced the two motivational orientations and elicited judgments of similarities (Experiments 1 and 2) and differences (Experiment 2) for pairs of pictures. Results confirmed the hypothesis. We propose that the relative attunement to similarities/differences under approach/avoidance is functional because it allows for a flexible conceptualization of the environment/an ability to discern slight deviations from what is expected.     

Inhibition Efficiency in Highly Proficient Bilinguals and Simultaneous Interpreters: Evidence from Language Switching and Stroop Tasks

The present behavioral study aimed to examine the impact of language control expertise on two domain-general control processes, i.e. active inhibition of competing representations and overcoming of inhibition. We compared how Simultaneous Interpreters (SI) and Highly Proficient Bilinguals—two groups assumed to differ in language control capacity—performed executive tasks involving specific inhibition processes. In Experiment 1 (language decision task), both active and overcoming of inhibition processes are involved, while in Experiment 2 (bilingual Stroop task) only interference suppression is supposed to be required. The results of Experiment 1 showed a language switching effect only for the highly proficient bilinguals, potentially because overcoming of inhibition requires more cognitive resources than in SI. Nevertheless, both groups performed similarly on the Stroop task in Experiment 2, which suggests that active inhibition may work similarly in both groups. These contrasting results suggest that overcoming of inhibition may be harder to master than active inhibition. Taken together, these data indicate that some executive control processes may be less sensitive to the degree of expertise in bilingual language control than others. Our findings lend support to psycholinguistic models of bilingualism postulating a higher-order mechanism regulating language activation.     

Working memory in social anxiety disorder: better manipulation of emotional versus neutral material in working memory

Individuals with social anxiety disorder (SAD) engage in post-event processing, a form of perseverative thinking. Given that deficits in working memory might underlie perseverative thinking, we examined working memory in SAD with a particular focus on the effects of stimulus valence. SAD (n?=?31) and healthy control (n?=?20) participants either maintained (forward trials) or reversed (backward trials) in working memory the order of four emotional or four neutral pictures, and we examined sorting costs, which reflect the extent to which performance deteriorated on the backward trials compared to the forward trials. Emotionality of stimuli affected performance of the two groups differently. Whereas control participants exhibited higher sorting costs for emotional stimuli compared to neutral stimuli, SAD participants exhibited the opposite pattern. Greater attention to emotional stimuli in SAD might facilitate the processing of emotional (vs. neutral) stimuli in working memory.     

Reinforcement,Rationality, and Intentions: How Robust Is Automatic Reinforcement Learning in Economic Decision Making?

Reinforcement learning is often observed in economic decision making and may lead to detrimental decisions. Because of its automaticity, it is difficult to avoid. In three experimental studies, we investigated whether this process could be controlled by goal intentions and implementation intentions. Participants' decisions were investigated in a probability‐updating task in which the normative rule to maximize expected payoff (Bayes' rule) conflicted with the reinforcement heuristic as a simple decision rule. Some participants were asked to set goal intentions designated to foster the optimization of rational decision making, while other participants were asked to furnish these goal intentions with implementation intentions. Results showed that controlling automatic processes of reinforcement learning is possible by means of goal intentions or implementation intentions that focus decision makers on the analysis of decision feedback. Importantly, such beneficial effects were not achieved by simply instructing participants to analyze the feedback, without defining a goal as the desired end state from a first‐person perspective. Regarding intentions supposed to shut down reinforcement processes by controlling negative affect, effects were more complex and depended on the specified goal‐directed behavior. The goal intention to suppress the disappointment elicited by negative feedback was not effective in controlling reinforcement processes. Furnishing this goal with an implementation intention even backfired and strengthened unwanted reinforcement processes. In contrast, asking participants to keep cool in response to negative decision outcomes through the use of goal intentions or implementation intentions increased decisions in line with Bayes' rule.

Nonlinear associations between job insecurity and adaptive performance: The mediating role of negative affect and negative work reflection

This study aimed at investigating the association between employee-rated job insecurity and supervisor-rated adaptive performance. We hypothesized a nonlinear association between job insecurity and adaptive performance, expecting negative affect and negative work reflections to mediate this relationship. Using a sample of 131 employee–supervisor dyads, path analysis revealed a curvilinear relation between job insecurity and supervisor-rated adaptive performance, indicating medium job insecurity being linked to the lowest adaptive performance. Bootstrapping confirmed that negative affect and negative work reflection both mediated the nonlinear association between job insecurity and adaptive performance. After a time lag of 16 weeks, 71 supervisors again rated their employees’ adaptive performance. Path analysis confirmed a nonlinear association between employees’ job insecurity (T1) and supervisor-rated adaptive performance (T2). Theoretical and practical implications are discussed.     

What is it to Depsychologize Psychology?

In this essay, I distinguish two ways of depsychologizing psychology: ‘anti‐psychologism’ and ‘non‐psychologism’. Both positions are responses to the Fregean sharp distinction between the logical and the psychological. But where anti‐psychologism, which I find in John McDowell, attempts to overcome the sharp distinction by arguing that psychological states and their expressions are apt to be articulated into judgments, Stanley Cavell's non‐psychologism, a powerful and neglected alternative, wants to overcome the sharp distinction by abandoning judgment as the paradigm expression of thought and communication.     

Heart Rate Recovery After Exercise in Outpatients with Coronary Heart Disease: Role of Depressive Symptoms and Positive Affect

Heart rate recovery after 1 min of exercise cessation (HRR-1) is an important prognostic factor in patients with cardiovascular disease (CVD). We aimed to further elucidate the association between HRR-1 and known psychosocial risk factors in patients referred for comprehensive cardiac rehabilitation. We examined 521 patients with coronary heart disease in the first week of an outpatient cardiac rehabilitation program. Depressive and anxiety symptoms were measured with the Hospital Anxiety and Depression Scale, and positive (PA) and negative affect were rated with the Global Mood Scale. Depressive symptoms showed a significant inverse relationship with HRR-1 (p?<?.05), controlling for sociodemographic and medical covariates, whereas anxiety symptoms did not show a significant association. PA made a significant contribution to HRR-1 as well (p?<?.05). Our findings suggest an independent association between HRR-1 and psychosocial risk factors of CVD.
