Relationships of career adaptabilities with explicit and implicit self-concepts

Career adaptability is a psychosocial construct that incorporates a set of essential resources to one's career development. The adaptability resources' relevance is even higher when it comes to former communist countries, such as Romania, where job security and stability were seen as central benefits for workers. The aim of this study was to provide a more comprehensive understanding of the stable underpinnings of career adaptabilities by exploring their relationships with aspects of the self that are driven by automatic processes and that are less affected by self-presentation biases. A sample of 359 participants completed the Career Adapt Abilities Scale (CAAS)-Romanian form, out of which a subsample of 212 participants also completed a set of scales comprising explicit and implicit measures of conscientiousness, extraversion, neuroticism, and self-esteem. Results revealed nonsignificant additive contributions of the implicit self-concept measures over what was already explained by the explicit self-concepts. The most noticeable effect resides in the significant interaction between explicit and implicit self-esteem in relation to control, confidence, and overall adaptability. These results reveal that individuals with high explicit and low implicit self-esteem perceive themselves as being the most adaptable. Notably, these results were obtained using a Romanian version of CAAS that possesses very good psychometric properties (i.e., excellent internal consistencies, the same four-factor multidimensional solution, replicated patterns of associations between CAAS and explicit self-concepts of personality).     

Behavioral variability in an evolutionary theory of behavior dynamics

McDowell’s evolutionary theory of behavior dynamics (McDowell, 2004) instantiates populations of behaviors (abstractly represented by integers) that evolve under the selection pressure of the environment in the form of positive reinforcement. Each generation gives rise to the next via low‐level Darwinian processes of selection, recombination, and mutation. The emergent patterns can be analyzed and compared to those produced by biological organisms. The purpose of this project was to explore the effects of high mutation rates on behavioral variability in environments that arranged different reinforcer rates and magnitudes. Behavioral variability increased with the rate of mutation. High reinforcer rates and magnitudes reduced these effects; low reinforcer rates and magnitudes augmented them. These results are in agreement with live‐organism research on behavioral variability. Various combinations of mutation rates, reinforcer rates, and reinforcer magnitudes produced similar high‐level outcomes (equifinality). These findings suggest that the independent variables that describe an experimental condition interact; that is, they do not influence behavior independently. These conclusions have implications for the interpretation of high levels of variability, mathematical undermatching, and the matching theory. The last part of the discussion centers on a potential biological counterpart for the rate of mutation, namely spontaneous fluctuations in the brain's default mode network.     

An Examination of Concurrent and Incremental Validity of Four Mindfulness Scales

General consensus among psychologists supports the beneficial effects of mindfulness in the treatment of a wide range of clinical conditions such as personality, mood, and anxiety disorders. Several scales used to assess this psychological construct, mainly rooted in Eastern traditions, are currently available to researchers and clinicians. However, the conceptualization and measurement of mindfulness has been considerably diverse. The present study examines the concurrent and incremental validity of four scales: the Philadelphia Mindfulness Scale (PHLMS), the Toronto Mindfulness Scale (TMS), the Five-Facet Mindfulness Questionnaire (FFMQ), and the Langer Mindfulness Scale (LMS). Two independent samples of 176 adults and 397 students, respectively, were recruited. With few exceptions, results were consistent across the two samples and indicated that measures based on an Eastern conceptualization of mindfulness (TMS, PHLMS, and FFMQ) show a different pattern of association with the chosen outcomes compared to the LMS, which is based on a Western conceptualization. Overall, the PHLMS showed the strongest predictive effects and the LMS the weakest in terms of both number of predicted criteria and average effect size. Implications for research and practice are discussed.     

Dispositional Optimism and Judgments of Future Life Events: Affective States as Moderators

This research examined the relation between dispositional optimism and judgments of future life events and whether this relation is moderated by affective states. In this study the moderating role of experimentally induced affective states, using film clips (N = 259), was investigated. After filling in the questionnaire for dispositional optimism, the participants were randomly assigned in the experimental conditions in order to induce positive versus negative affective states. Finally, the participants filled in the affective states and judgments of future life events scales. The results indicated that the participants with a higher level of optimism had the tendency to judge positive events as more likely and negative events as less likely to happen in the future. We found evidence for affective states as moderators; the association between dispositional optimism and judgments of future positive events depended on experimentally induced affective states. Specifically, in positive affective state condition, the association between dispositional optimism and judgments of future positive events was weaker than in both negative affective state and control conditions. The implications of these findings for understanding the role of optimism and affective states, in determining the judgments about the likelihood of future events are discussed.     

Who is good at this game? Linking an activity to a social category undermines children's achievement

Children's achievement-related theories have a profound impact on their academic success. Children who adopt entity theories believe that their ability to perform a task is dictated by the amount of natural talent they possess for that task--a belief that has well-documented adverse consequences for their achievement (e.g., lowered persistence, impaired performance). It is thus important to understand what leads children to adopt entity theories. In the experiments reported here, we hypothesized that the mere act of linking success at an unfamiliar, challenging activity to a social group gives rise to entity beliefs that are so powerful as to interfere with children's ability to perform the activity. Two experiments showed that, as predicted, the performance of 4- to 7-year-olds (N = 192) was impaired by exposure to information that associated success in the task at hand with membership in a certain social group (e.g., "boys are good at this game"), regardless of whether the children themselves belonged to that group.     

Natural extinction: A criterion shift phenomenon

Previous detection performances obtained in a multi-varied contrast environment showed that observers tend to report significantly less the occurrence of the relatively lower contrast targets and significantly more the occurrence of the higher contrast ones than in conditions where each of these stimuli was tested in isolation (Gorea & Sagi, 2000). This criterion shift phenomenon is a form of contrast-dependent extinction in normal observers. To add more ground to the analogy between this type of “natural” extinction and the stroke-related one, we present a series of experiments where identical targets are displayed (1) at the same eccentricity but in opposite hemifields (along both the horizontal and vertical meridians), (2) at different eccentricities, and (3) where different spatial frequency targets of equal contrasts are displayed at the same eccentricity. Hemifield, eccentricity, and spatial frequency manipulations were intended to entail sensitivity differences for identical contrast stimuli. Some observers showed up to 3 and 1.5 d'-units differences between their left and right and between their upper and lower hemifields, respectively. Although observers may show significant response biases even for isolated stimuli as well as for equally visible ones presented together, it is always the case that they use higher response criteria (extinction) for the less visible targets and lower response criteria for the more visible ones (counter-extinction) when these stimuli are mixed in one experimental block. The observed criterion shifts translate into as much as three times more “Not seen” responses for the less visible targets and into about 1.3 times more “Seen” responses for the more visible ones. Taken together, the present data support the notion that at least some forms of extinction (and perhaps neglect) are contingent on relative sensory/perceptual impairments and that they reflect more or less drastic forms of criterion/decision shifts.     

The Social Structure of Political Echo Chambers: Variation in Ideological Homophily in Online Networks

We predict that people with different political orientations will exhibit systematically different levels of political homophily, the tendency to associate with others similar to oneself in political ideology. Research on personality differences across the political spectrum finds that both more conservative and more politically extreme individuals tend to exhibit greater orientations towards cognitive stability, clarity, and familiarity. We reason that such a “preference for certainty” may make these individuals more inclined to seek out the company of those who reaffirm, rather than challenge, their views. Since survey studies of political homophily face well‐documented methodological challenges, we instead test this proposition on a large sample of politically engaged users of the social‐networking platform Twitter, whose ideologies we infer from the politicians and policy nonprofits they follow. As predicted, we find that both more extreme and more conservative individuals tend to be more homophilous than more liberal and more moderate ones.     

Introspective duration estimation of reactive and proactive motor responses

The metajudgment of motor responses refers to our ability to evaluate the accuracy of our own actions. Can humans metajudge the duration of their Reaction Times (RTs) to a light-flash and the accuracy of their reproduction of a reference time interval bounded by two light flashes (Anticipatory Response Time, ART)? A series of four distinct experiments shows that RT_Meta and ART_Metajudgments are possible but with accuracies about ×2.4 and ×3 poorer than the corresponding RT and ART ones. In order to reveal the origin of this drop in performance, we ask whether a visual feedback synchronous with subjects’ key-presses could improve performance. We show that overall the presence of a visual feedback does not significantly improve metajudgment accuracy although such a trend is noticeable in ART_Meta. We then compare these performances with the passive perceptual estimation of the played back (Pb) RT and ART time intervals when bounded by two (RT_Pb) and three (ART_Pb) light flashes. We show that RT_Meta and RT_Pb accuracies are close to equal, but that ART_Meta is about ×2 less accurate than ART_Pb which in turn is ×1.5 less accurate than ART. The latter observation fails however to reach statistical significance hence not sustaining proposals that active time estimation is more reliable than passive one. The whole dataset is accounted for by a clock-type model where duration estimation performance is limited by four noise sources (visual, clock-count, motor and proprioceptive + efference copy) plus one proper to ART_Meta task. It is proposed that the latter reflects the impossibility for the time-counting system to use the same time origin more than once.
