Effects of decision-phase time constraints on emotion-based learning in the Iowa Gambling Task

Research employing the Iowa Gambling Task (IGT) has frequently shown that learning is impaired in various clinical populations. However, precisely what constitutes "unimpaired" control group learning remains unclear. In order to understand some of the possible factors underlying variability in control group IGT performance, the present study sought to manipulate features of the task to intentionally disrupt learning. Specifically, the present study investigated the effects of time constraints on emotion-based learning during automated administration of the IGT. For two groups of participants, a time-constraint of either 2-s or 4-s was implemented during the critical decision making period, while a control group received no time constraint. We also evaluated participants' subjective experience after every block of 20 trials. Results demonstrated that the 2-s group differed significantly from the control group. Subjective experience measures revealed rapid development of awareness of the advantageous and disadvantageous decks among all three groups. Overall, our findings demonstrate, for the first time, the effects of decision-phase time constraints on emotion-based learning and indicate that the IGT reward/punishment schedules are to some extent cognitively penetrable.     

Changes in within- and between-person associations between basic psychological need satisfaction and well-being after retirement

Satisfaction of the basic psychological needs for autonomy, competence and relatedness is associated with higher well-being. However, little is known about change or stability in this association over the life span. We therefore investigated changes in the association between well-being and basic psychological need satisfaction in the retirement transition. Data was drawn from four waves of the Health, Aging, and Retirement Transitions in Sweden (HEARTS) study (N = 5,074, M (age) = 63.16; 53.61% female). Multi-level models were conducted and the analyses revealed evidence for continuity as well as systematic changes in within- and between-person associations across the retirement transition. Our findings demonstrate the benefits of applying a longitudinal design and a life span perspective on basic psychological need satisfaction.     

Subjective career success: A meta-analytic review

This study proposes that employees have to face a variety of obstacles over the course of their careers, each of which can create stress for employees and, in so doing, lower their subjective career success (SCS). Using a meta-analysis of 216 samples published over the past three decades (N = 94,090), we found that career hurdles associated with dispositional traits (e.g., low emotional stability), motivation (e.g., low work engagement), social networks (e.g. low supervisor support), and organizational and job support (e.g., job insecurity) were all significantly related to lower SCS. Counter to expectations, background-related hurdles (e.g., being female) and skill-related hurdles (e.g., lack of job changes and international experience) were not significantly related to SCS.     

Scaling happiness

This paper focuses on a particular method which is used in contemporary empirical happiness studies, namely measuring people's happiness by scoring their emotions (Kahneman is a prominent scholar). I examine the presupposition in this field that emotion scores can be added or subtracted, that throughout affective space runs a straight axis that plots hedonic tone or pleasure.     

L’âge subjectif en contexte de formation. Étude auprès d’une population estudiantine roumaine

Subjective age is a little-used variable in psychological research, in spite of being considered by numerous authors a more accurate indicator as compared to the chronological age. The current research aims to concentrate on the subjective age of the students while in their formation years and to identify the connections that it establishes with their chronological age and their subjective age in general. Two hundred and twenty-eight students from the university of Brasov, aged between 18 and 56 answered two questionnaires (the Romanian adaptation of the Staitz and McClay (1998) questionnaire and the adaptation of the same questionnaire to the context of academic formation). The questionnaires were separated by another one, administered for relaxation purposes. The results show that there exists a subjective age during the formation years, which is different from, but nonetheless correlated to the chronological age and to the subjective age in general. The results bring forward the impact of the context, in the given situation an academic one, on the age that one gives himself.     

Temporal fluctuations in driving demand: The effect of traffic complexity on subjective measures of workload and driving performance

Traffic density has been shown to be a factor of traffic complexity which influences driver workload. However, little research has systematically varied and examined how traffic density affects workload in dynamic traffic conditions. In this driving simulator study, the effects of two dynamically changing traffic complexity factors (Traffic Flow and Lane Change Presence) on workload were examined. These fluctuations in driving demand were then captured using a continuous subjective rating method and driving performance measures. The results indicate a linear upward trend in driver workload with increasing traffic flow, up to moderate traffic flow levels. The analysis also showed that driver workload increased when a lane change occurred in the drivers’ forward field of view, with further increases in workload when that lane change occurred in close proximity. Both of these main effects were captured via subjective assessment and with driving performance parameters such as speed variation, mean time headway and variation in lateral position. Understanding how these traffic behaviours dynamically influence driver workload is beneficial in estimating and managing driver workload. The present study suggests possible ways of defining the level of workload associated with surrounding traffic complexity, which could help contribute to the design of an adaptive workload estimator.     

The experience of new sensorimotor contingencies by sensory augmentation

Embedded in the paradigm of embodied cognition, the theory of sensorimotor contingencies (SMCs) proposes that motor actions and associated sensory stimulations are tied together by lawful relations termed SMCs. We aimed to investigate whether SMCs can be learned by means of sensory augmentation. Therefore we focused on related perceptual changes. Subjects trained for 7 weeks with the feelSpace belt mapping information of the magnetic north to vibrotactile stimulation around the waist. They experienced substantial changes in their space perception. The belt facilitated navigation and stimulated the usage of new navigation strategies. The belt’s vibrating signal changed to a kind of spatial information over time while the belt’s appeal and perceived usability increased. The belt also induced certain emotional states. Overall, the results show that learning new SMCs with this relatively small and usable device leads to profound perceptual and emotional changes, which are fully compatible with embodied theories of cognition.     

A comparison between a visual analogue scale and a four point scale as measures of conscious experience of motion

Can participants make use of the large number of response alternatives of visual analogue scales (VAS) when reporting their subjective experience of motion? In a new paradigm, participants adjusted a comparison according to random dot kinematograms with the direction of motion varying between 0° and 360°. After each discrimination response, they reported how clearly they experienced the global motion either using a VAS or a discrete scale with four scale steps. We observed that both scales were internally consistent and were used gradually. The visual analogue scale was more efficient in predicting discrimination error but this effect was mediated by longer report times and was no longer observed when the VAS was discretized into four bins. These observations are consistent with the interpretation that VAS and discrete scales are associated with a comparable degree of metacognitive sensitivity, although the VAS provides a greater amount of information.     

Collaboration inflation: Egocentric source monitoring errors following collaborative remembering

Following collaborative remembering, people may adopt their partner's contributions as their own memory. In two studies, we asked people to study partially overlapping lists of words. During collaborative remembering, dyads either worked to include all words no matter who studied them or limited recall to only words studied by both dyad members. This differential focus on source information during collaborative recall impacted performance on a later source memory test. Nonetheless we found frequent source monitoring errors that displayed an egocentric bias. People were more likely to claim their partner's contributions as their own memories than attribute their memories to their partners. In collaborative remembering, people work to construct an agreed upon version of the past that quickly becomes each individual's memory.     

Remembering stories together: Social contagion and the moderating influence of disagreements in conversations

Although remembering often occurs with conversations, the effects of its pragmatics on memory are rarely examined. We studied the effect of two pragmatic factors: (1) the presence of disagreeing and (2) the level of participation in the disagreement. In the present study, each participant read a slightly different version of four stories, thereby allowing for the possibility of social contagion through the conversation. They then jointly recounted the stories. We coded for the presence or absence of disagreements, and whether a participant contributed to the disagreement. Three factors mediated social contagion: (a) the presence or absence of an overt disagreement; (b) whether or not a member of a conversational remembering participated actively in a disagreement; and (c) how well participants remembered the original material. Both the pragmatics of conversations and quality of memory are important factors moderating social contagion.
