Jealousy at work: The role of rivals’ characteristics
2018
The present study examined rival characteristics that may evoke jealousy in the workplace, differences between men and women in this regard, and the relationship between jealousy responses and intrasexual competitiveness and social comparison orientation. Participants were 426 male and female employees. By means of a questionnaire, participants were presented with a jealousy-evoking scenario after which jealousy responses to 24 rival characteristics were assessed. Findings showed that a rival's social communal attributes evoked highest levels of jealousy, and that, compared to men, women reported more jealousy in response to a rival's physical attractiveness. Overall, as individuals had hig…
Burnout during a long-term rehabilitation: comparing low burnout, high burnout - benefited, and high burnout - not benefited trajectories.
2009
To focus rehabilitation activities among burnout clients more effectively, it is important to investigate who benefits from burnout interventions. This study (N=85) aimed at identifying burnout trajectories in terms of benefit, that is, subgroups of clients who share similar mean levels and changes in burnout during a one-year rehabilitation intervention (17 days in total) with a six-month follow-up. After identifying the burnout trajectories, the relations of the trajectories with factors describing the clients, antecedents, and consequences of burnout during the one-year intervention were examined. Three burnout trajectories were identified by growth mixture modeling: (a) low burnout (n=3…
Can colours be used to segment words when reading?
2015
Rayner, Fischer, and Pollatsek (1998, Vision Research) demonstrated that reading unspaced text in Indo-European languages produces a substantial reading cost in word identification (as deduced from an increased word-frequency effect on target words embedded in the unspaced vs. spaced sentences) and in eye movement guidance (as deduced from landing sites closer to the beginning of the words in unspaced sentences). However, the addition of spaces between words comes with a cost: nearby words may fall outside high-acuity central vision, thus reducing the potential benefits of parafoveal processing. In the present experiment, we introduced a salient visual cue intended to facilitate the process…
Tower of Hanoi and working memory in adult persons with intellectual disability
2001
Persons with intellectual disability (ID) have been found to perform more poorly than their mental age would suggest in the visuo-spatial problem solving task Tower of Hanoi (TOH). Inefficient performance has been assumed to be related to inability to use sophisticated problem solving strategies because of restricted working memory capacity. In the present study, the TOH performance of adult persons with ID was found to be equal to that of fluid-intelligence-matched general children. However, persons with ID violated the rules of the TOH more often, and needed more trials to solve the TOH problems than the children did. Visuo-spatial and executive working memory tasks were significantly con…
Conditional reasoning by mental models: chronometric and developmental evidence
2000
The aim of this article is to verify two predictions resulting from the mental models theory of conditional reasoning. First, the denial of antecedent (DA) and modus tollens (MT) inferences should take longer to verify than modus ponens (MP) and affirmation of consequent (AC) because the former require subjects to flesh out the initial model whereas the latter do not. This prediction was confirmed in two reaction time experiments in adults. In line with Evans' proposal (Evans, J. St. B. T. (1993). The mental model theory of conditional reasoning: critical appraisal and revision. Cognition, 48, 1-20), there was a strong directionality effect: inferences from antecedent to consequent (MP and …
Effects of a short video feedback intervention on enhancing maternal sensitivity and infant development in low-income families
2019
This study evaluated the effects of a short video feedback intervention aimed at enhancing maternal sensitivity and the development of infants from low-income families in a randomized controlled trial. Forty-four mother-infant dyads living in low-income communities from Salvador, Brazil were randomly assigned between intervention and control groups. Maternal sensitivity was assessed during free-play and infant development was evaluated with a standardized scale. Intervention took place in eight home visits between the infant's third and tenth month. Results showed mothers in the intervention group interpreted the meaning of their infants' behavior more often (r = 0.33), asked babies more qu…
Size invariance in visual number discrimination
1991
This study deals with the observer's ability to discriminate the numerosity of two random dot-patterns irrespective of their relative size. One of these two patterns was a reference one that was always composed of 32 dots randomly distributed within a K x K invisible square window (K = 1.92 degrees). The second one was the test pattern with one of the five magnifications (K = 0.64 degrees, 1.28 degrees, 1.92 degrees, 2.56 degrees, 3.20 degrees) and the relative number of dots varied on 11 levels (N = -15, -12, -9, -6, -3, 0, 3, 6, 9, 12, or 15 dots). The observer's task was to indicate which of the two patterns contained more dots. The results show that the stimulus size, as an irrelevant s…
Effects of a vestibular physiotherapy protocol on adults with intellectual disability in the prevention of falls: A multi-centre clinical trial
2018
Background Balance alterations are one of the main problems in people with intellectual disabilities (ID), increasing their risk of falls and impacting their life. Aims To describe a vestibular rehabilitation programme (VRP) and evaluate its effects on the ability to maintain balance and risk of suffering a fall. Methods Forty-seven adults with mild to moderate ID were randomly assigned to two groups: a control group (CG, N = 24), which performed a general physical exercise only, and an experimental group (EG, N = 23) which also completed a VRP. The variables, used pre- and post-training and 1 month after the intervention, were as follows: Center of Pressure Displacement, Berg Scale, Timed …
Identification and location tasks rely on different mental processes: a diffusion model account of validity effects in spatial cueing paradigms with …
2018
Spatial cueing paradigms are popular tools to assess human attention to emotional stimuli, but different variants of these paradigms differ in what participants' primary task is. In one variant, participants indicate the location of the target (location task), whereas in the other they indicate the shape of the target (identification task). In the present paper we test the idea that although these two variants produce seemingly comparable cue validity effects on response times, they rest on different underlying processes. Across four studies (total N = 397; two in the supplement) using both variants and manipulating the motivational relevance of cue content, diffusion model analyses reveale…
Criminological differences between child pornography offenders arrested in Spain.
2019
Abstract Background Lack of studies on CP offenders from non-English speaking countries motivated the analysis of the profile of adult men arrested in Spain for such crimes (N = 347). Objective The current study examined differences between groups of CP users according to their criminal history (i.e., CP-only offenders, CP offenders with other nonviolent or non-sexually violent crimes, and dual offenders). Methods Analyses of case investigation files were performed across seven key areas: (1) sociodemographic characteristics, (2) criminological data, (3) characteristics of index CP offending, (4) characteristics of CP collections, (5) access to children, (6) indication of pedophilic or hebe…
