The fundamental need to belong: on the distinction between growth and deficit-reduction orientations

The need for belongingness (the universal need to form and maintain positive, stable interpersonal relationships) has led to much research over the past decade. Although such a need is universal, some qualitative differences exist in its orientation. Specifically, two belongingness need orientations are proposed: a growth orientation (a belongingness need directed toward interpersonal actualization) and a deficit-reduction orientation (a belongingness need directed toward interpersonal deficit reduction or repair). It is hypothesized that a deficit-reduction orientation to the need to belong is associated with lower levels of intrapersonal and interpersonal psychological functioning compared to a growth orientation. The results of a series of four studies supported the proposed hypotheses. Implications of the proposed model for future research on the need to belong are discussed.     

Contemporary theories of 1/f noise in motor control

1/f noise has been discovered in a number of time series collected in psychological and behavioral experiments. This ubiquitous phenomenon has been ignored for a long time and classical models were not designed for accounting for these long-range correlations. The aim of this paper is to present and discuss contrasted theoretical perspectives on 1/f noise, in order to provide a comprehensive overview of current debates in this domain. In a first part, we propose a formal definition of the phenomenon of 1/f noise, and we present some commonly used methods for measuring long-range correlations in time series. In a second part, we develop a theoretical position that considers 1/f noise as the hallmark of system complexity. From this point of view, 1/f noise emerges from the coordination of the many elements that compose the system. In a third part, we present a theoretical counterpoint suggesting that 1/f noise could emerge from localized sources within the system. In conclusion, we try to draw some lines of reasoning for going beyond the opposition between these two approaches.     

Test-retest reliability of the Frankfurt Complaint Questionnaire

Long-term reliability of the Frankfurt Complaint Questionnaire (FCQ) was investigated in two follow-up studies of participants with psychosis using a test-retest method. In the first study (N = 56), the duration of the follow-up ranged from 6 months to 2 years; Spearman rho was .62 for the abridged (18 items) Spanish version of the questionnaire. In Study 2 (N = 21), in participants with stable schizophrenia, the follow-up ranged from 8 to 11 years; test-retest Spearman rho was .83 for the French version of the questionnaire. Subjective experiences could constitute, in psychosis-prone people, traits or markers of psychotic vulnerability.     

Genetic testing for hereditary cancer: effects of alexithymia and coping strategies on variations in anxiety before and after result disclosure

This study assessed the impact of the results of genetic testing for hereditary cancer from a multifactorial health psychology perspective, considering that emotional expression plays a key role in psychological adjustment. Measures of dispositional and transactional coping strategies, anxiety and alexithymia were filled out by 77 participants in a longitudinal study design. Statistical analyses were performed using general linear models and partial least squares path modelling, low-constraint methods that are particularly useful in the behavioural sciences. While anxiety levels prior to the result announcement were predictive of the distress experienced by noncarriers, considerable variability was observed for mutation carriers. Some subjects who had lower anxiety levels before the test displayed greater anxiety afterwards, but others seemed to anticipate the distress they would experience with the result that they showed a decrease in anxiety. The mutation carriers behaved as though their adaptive functioning were reshaped by the test result, independent of their disposition and previous emotional state, except in the case of alexithymia. Difficulty expressing emotions prior to genetic testing contributed to a similar difficulty after receiving the result, adding to the latter's emotional impact by promoting emotion-focused coping strategies and increasing distress.     

The role of goal representation in preschoolers' flexibility and inhibition

This study addressed the role of goal representation in preschoolers’ inhibition and flexibility performance. A total of 56 4- and 5-year-olds were tested in an adapted version of the Shape School task where the difficulty of goal representation was manipulated by varying the degree of transparency of task cues. The findings showed that both age groups’ performance in the flexibility phase was increased when demands on goal representation were alleviated by using transparent cues instead of arbitrary cues. Furthermore, 4-year-olds performed more accurately on go trials in the inhibition phase with transparent cues than with arbitrary cues. These results confirm the critical role of goal representation in flexibility and reveal its influence in inhibition contexts. Altogether, this study suggests that goal representation is a key element for efficient executive function across a variety of settings involving different executive functions.     

Cognitive abilities explaining age-related changes in time perception of short and long durations

The current study investigated how the development of cognitive abilities explains the age-related changes in temporal judgment over short and long duration ranges from 0.5 to 30 s. Children (5- and 9-year-olds) as well as adults were given a temporal bisection task with four different duration ranges: a duration range shorter than 1 s, two duration ranges longer than 3 s (4-8 s and >15 s), and an intermediate duration range (1.25-2.5 s). Their cognitive abilities were also assessed using a series of neuropsychological tests. The results showed that temporal sensitivity improved with age for each duration range but that this improvement occurred earlier for the short durations than for the long durations. Furthermore, the results revealed that the age-related improvement in time sensitivity for the durations shorter than 1 s was explained by the development of short-term memory span, whereas that for long durations was explained by the development of attention/executive functions. To summarize, the development of the abilities required to process long durations seems to be explained mainly by the development of attentional resources.     

Intentional subitizing: exploring the role of automaticity in enumeration

Subitizing is traditionally described as the rapid, preattentive and automatic enumeration of up to four items. Counting, by contrast, describes the enumeration of larger sets of items and requires slower serial shifts of attention. Although recent research has called into question the preattentive nature of subitizing, whether or not numerosities in the subitizing range can be automatically accessed is yet to be empirically tested. In the current study, participants searched for two pre-defined digits in a circular visual-search array. Distractor dots of various set sizes were placed at the centre of the array. Despite the relevance of the distractor numerosities to the target detection task, the distractors did not influence target detection, thereby suggesting that their numerosities were not automatically accessed in Experiment 1. In Experiment 2, participants were explicitly instructed to enumerate the distractor dots. Here, congruent and incongruent distractor numerosities influenced the target detection task, thereby revealing that the distractor dots were capable of generating interference. Experiment 3 ensured that dots were attended by asking participants to detect the luminance of dots. Data confirmed that subitizing was not automatic. The present study also supported the alleged discontinuity between the subitizing and counting ranges because an examination of reaction time gradients in Experiment 2 found the counting gradient to be significantly steeper than the subitizing gradient. In sum, the results suggest that subitizing is a distinct but non-automatic style of enumeration.     

Temperament Alters Susceptibility to Negative Peer Influence in Early Adolescence

The role of deviant peers in adolescent antisocial behavior has been well documented, but less is known about individual differences in susceptibility to negative peer influence. This study examined whether specific temperament dimensions moderate the prospective relationship between peer deviance and delinquent behavior in early adolescence. Participants included 704 adolescents recruited from the community. At baseline, parents provided information on adolescents’ temperament and youth reported on their own and their friends’ delinquent behavior. Self-reports of adolescents’ delinquent behavior were collected again 16 months later. Peer deviance was related to delinquent behavior over time more strongly for adolescents with low levels of task orientation, flexibility, and positive mood, compared to youth with high levels of task orientation, flexibility, and positive mood. Analyses of gender differences indicated that low flexibility increased susceptibility to negative peer influence only for males, but not females. General activity level and sleep rhythmicity did not moderate the effect of peer behavior on delinquency.
