The Emotional Timeline of Unemployment: Anticipation,Reaction, and Adaptation

Unemployment continues to be one of the major challenges in industrialized societies. Aside from its economic and societal repercussions, questions concerning the subjective experience of unemployment have recently attracted increasing attention. Although existing studies have documented the detrimental effects of unemployment for cognitive (life satisfaction) and affective well-being, studies directly comparing these two dimensions of subjective well-being and their temporal dynamics in anticipation of and response to unemployment are absent from the literature. Using longitudinal data of the German Socio-Economic Panel (SOEP) and applying fixed effects regressions, we investigate changes in cognitive and affective well-being prior to and after job loss. Extending previous studies, we use discrete emotion measures instead of affect balance indicators to assess affective well-being. Our results support existing findings that unemployment leads to decreases in life satisfaction and that the unemployed do not adapt towards previous levels of life satisfaction. We also find that individuals more often experience sadness and anxiety, and less often happiness when transitioning into unemployment. Importantly, changes in affective well-being are less enduring compared to the changes in life satisfaction.     

Bringing color to emotion: The influence of color on attentional bias to briefly presented emotional images

Is color a critical feature in emotional content extraction and involuntary attentional orienting toward affective stimuli? Here we used briefly presented emotional distractors to investigate the extent to which color information can influence the time course of attentional bias in early visual cortex. While participants performed a demanding visual foreground task, complex unpleasant and neutral background images were displayed in color or grayscale format for a short period of 133 ms and were immediately masked. Such a short presentation poses a challenge for visual processing. In the visual detection task, participants attended to flickering squares that elicited the steady-state visual evoked potential (SSVEP), allowing us to analyze the temporal dynamics of the competition for processing resources in early visual cortex. Concurrently we measured the visual event-related potentials (ERPs) evoked by the unpleasant and neutral background scenes. The results showed (a) that the distraction effect was greater with color than with grayscale images and (b) that it lasted longer with colored unpleasant distractor images. Furthermore, classical and mass-univariate ERP analyses indicated that, when presented in color, emotional scenes elicited more pronounced early negativities (N1–EPN) relative to neutral scenes, than when the scenes were presented in grayscale. Consistent with neural data, unpleasant scenes were rated as being more emotionally negative and received slightly higher arousal values when they were shown in color than when they were presented in grayscale. Taken together, these findings provide evidence for the modulatory role of picture color on a cascade of coordinated perceptual processes: by facilitating the higher-level extraction of emotional content, color influences the duration of the attentional bias to briefly presented affective scenes in lower-tier visual areas.     

One executive function never comes alone: monitoring and its relation to working memory,reasoning, and different executive functions

Monitoring is involved in many daily tasks and is described in several theoretical approaches of executive functioning. This study investigated the relative relationship of cognitive processes that are theoretically relevant to monitoring, such as concept formation, reasoning, working memory, and general cognitive control functions. Data from 699 participants who performed the Balanced Switching Task, aiming at capturing monitoring, were used. Subsamples also performed standard tasks assessing the processes assumed to be related to monitoring. Structural equation modeling revealed that general cognitive control processes are particularly relevant. They mediate the relationship between working memory, reasoning, and monitoring. Updating and maintaining information, as well as concluding from information which strategies can guide behavior toward predefined goals, is required for the ability to exert general cognitive control, which again may be relevant for implementing strategies in a goal-directed way. Together, these processes seem to be necessary to adequately monitor behavior in complex tasks.     

Complex prospective memory: development across the lifespan and the role of task interruption

Prospective memory (PM) reflects the product of cognitive processes associated with the formation, retention, delayed initiation, and execution of intentions. It has been proposed that developmental changes in PM across the lifespan are heavily dependent upon the developmental trajectory of executive control functions. This study is the first to apply a complex PM task to children, young adults, and older adults. The procedure allows for the assessment of each of the 4 phases of PM. During intention execution, the authors additionally manipulated whether participants had to actively interrupt attention to the current 'ongoing' task in order to switch to the execution of the next intended task. Group differences mirroring inverted U-shaped functions were observed in those phases conceptualized as relying on executive control (intention formation, initiation, and execution). Age differences in intention execution were substantially greater when active task interruption was necessary. The current study provides the first evidence of growth and decline of complex PM across the lifespan and suggests that the degree of inhibitory control needed to succeed in the task may be one factor underlying this development.     

The Differential Influence of Lexical Parameters on Naming Latencies in German. A Study on Noun and Verb Picture Naming

The present study investigates the effects of word category (nouns versus verbs) and their subcategories on naming latencies in German, with a focus on the influence of lexical parameters on naming performance. The experimental material met linguistic construction criteria and was carefully matched for age of spontaneous production, frequency, and name agreement. Additional lexical parameters (objective age-of-acquisition, word length, visual complexity, imageability) were obtained. The results demonstrated a clear effect of word category on naming latencies. This effect was supported by two different observations. First, there was evidence for category and subcategory effects in naming: nouns were named faster than verbs, and intransitive verbs were named faster than transitive verbs. Second, while objective age-of-acquisition (naming age) turned out to be an important predictor of reaction times for both word categories, naming latencies for nouns and verbs were affected differentially by other lexical parameters. The results are discussed with respect to current controversies on the noun-verb-asymmetry.     

Chronic perchlorate exposure impairs stickleback reproductive behaviour and swimming performance

We describe behavioural changes in two generations of threespine stickleback (Gasterosteus aculeatus) exposed to environmentally relevant concentrations of perchlorate. The first generation (G(0,2002)) was exposed as two-year-old adults to perchlorate in experimental groups ranging in concentration from less than the method detection limit (<1.1 ppb) to 18.6 ppm for up to 22 days during their courtship, spawning, egg guarding, and first five days of fry guarding. No differences were noted in the behaviour or reproductive output of these fish that were exposed as adults. However, perchlorate exposure throughout development caused widespread effects in the second generation (G(1,2003)), which was spawned and raised through sexual maturity in one of four nominal experimental groups (0, 30 and 100 ppm, and a 'variable' treatment that progressively increased from <1.1 ppb to approximately 60 ppm perchlorate). Dose-dependent effects were found during the G(1,2003)'s swimming and behavioural evaluations, including higher mortality rates among treated fish following stressful events. Perchlorate-exposed fish had higher failure rates during swimming trials and failed at lower flow rates than control fish. A number of treated fish exhibited seizures. Progressively fewer males completed benchmark metrics, such as nest building, spawning, nursery formation, or fry production, in a dose-dependent manner. Fewer males from higher treatments courted females, and those that did initiated courtship later and had a reduced behavioural repertoire compared to fish from lower treatments. The lowest observed adverse effect level (LOAEL) for swimming performance, reproductive behaviour, survivorship and recruitment was 30 ppm perchlorate (our lowest G(1,2003) treatment), and near complete inhibition of reproductive activity was noted among males raised in 100 ppm perchlorate. A small number of treated G(1,2003) females were isolated in aquaria, and some performed reproductive behaviour typical of males, such as biting, leading and zig-zagging in the presence of gravid females. These findings have profound implications for recruitment in wild fish populations exposed to perchlorate, and suggest that perchlorate may disrupt behaviour in other vertebrates as well.     

Adult age differences in function concept learning

Function concept learning and knowledge use was explored across adulthood. During training older and younger adults predicted an amount of physiological arousal produced as a negative and positive function of a chemical substance. Knowledge use was evaluated with two transfer conditions requiring a switch between contextual contingencies: a relationship inversion, predicting the chemical amount given the physiological arousal, and a change from graphic based to text based stimuli. Older adults were impaired in applying the negative slope concept. However, there was no relative deficit in switching between the negative and positive function slopes or inverting the learned relationship. Our results suggest that age-related differences in relational reasoning tasks vary not only with processing efficiency, but also task related conceptual knowledge.     

Cognitive processing of body and appearance words as a function of thin-ideal internalization and schematic activation

To better understand how women at risk of body image disturbance respond when their body concerns are activated, we examined attentional and memory biases in undergraduate women with high thin-ideal internalization, an identified risk factor for eating disorders, following priming of body and appearance concerns. Female undergraduates (N = 186) viewed photos of either sports cars or attractive swimsuit models, then completed the Lexical Decision Test, a word recall test, and questionnaires assessing thin-ideal internalization and eating disorder symptomatology. High thin-ideal internalizers did not exhibit cognitive biases predicted by cognitive models of eating disorders, even when their body and appearance concerns were primed by exposure to attractive models. Converging evidence suggests that high-risk non-clinical samples rarely exhibit cognitive biases characteristic of individuals with eating disorders, and, in fact, may actually incorporate ideal appearance into their schemas and preferentially attend to attractive stimuli.     

Cognitive Development in Young-old Type-2 Diabetes Patients: A Longitudinal Analysis From The “Interdisciplinary Longitudinal Study of Aging”

In the present study, we investigated cognitive status and cognitive development in young-old Type-2 diabetes patients. Extending previous research, using the sample of the ILSE study (“Interdisciplinary Longitudinal Study of Aging”), we applied a comprehensive cognitive test battery to 38 Type-2 diabetes patients (mean age at T1: 63 years) and 421 control participants and tested both cognitive status and longitudinal changes after four years in several cognitive domains (crystallized intelligence, verbal memory, visual memory, executive functioning, psychomotor speed, and fluid intelligence). Results revealed no cross-sectional group differences in any cognitive domain at T1 nor at T2. However, testing group differences in intraindividual change over time, reliable group differences in the change of crystallized intelligence and fluid intelligence were revealed. While controls improved in crystallized intelligence as well as in fluid intelligence over time, diabetes patients’ performance decreased. The results demonstrate that in young-old adults the effects of diabetes on cognition may only be detected by analyzing within-person changes instead of mean level differences.
