Validity of the Parenting Stress Index-Short Form in a sample of Spanish fathers

The purpose of this study was to analyze the psychometric properties of the Spanish version of the Parenting Stress Index-Short Form in a sample of 115 fathers of infants aged between ten and thirty-nine months old. The exploratory factor analysis revealed three reasonably distinct factors, as in the original version of the instrument. The three extracted factors: Parental Distress, Parent-Child Dysfunctional Interaction and Difficult Child accounted for 47.48 % of the variance. The internal consistency coefficients were high in each factor or subscale. These results provided empirical evidence in favour of the reliability and validity of the Parenting Stress Index-Short Form in Spanish fathers, and can be useful to elucidate the mechanisms through which stress impacts parenting and permitting to develop more targeted interventions for infants and their families.     

On Identifying Plausibility and Deliberative Public Policy

The identification of plausible epistemic approaches in science as well as the social problem definitions with which scientists implicitly work is essential for the quality of a deliberative public policy. While responding to the Nanofutures project, I will reflect on the essential elements of such a policy.     

Cognitive reappraisal in the context of oppression: implications for psychological functioning

Research on emotion regulation has shown cognitive reappraisal to be positively correlated with better psychological functioning. Prior research has failed to account for contextual influences on this important relationship. We examined how this relationship plays out across two United States ethnic groups that represent different contexts of oppression: Puerto Ricans, experiencing distal oppression (societal level) but not proximal oppression (immediate environment), and Latino Americans, experiencing both. We also captured individual beliefs regarding oppression of one's group and implications of that oppression by measuring oppressed minority ideology (OMI). Results confirmed our hypothesis that the relationship between reappraisal and psychological functioning would be moderated by the context of oppression (as measured by ethnic group membership and OMI). For Latino Americans high on OMI, reappraisal was negatively associated with psychological functioning. For Puerto Ricans, regardless of OMI, this relationship remained positive, suggesting a possible benefit for minorities in being surrounded by in-group members.     

Delighted and distracted: positive affect increases priming for irrelevant information

Emotional states are known to influence how people process relevant information. Here, we address the impact of emotional state on irrelevant information. In this experiment, participants were randomly assigned to a neutral or positive mood induction, and then completed a task that involved viewing a sequence of overlapping pictures and words. They were instructed to attend to the pictures and ignore the distracting words. Following a filled interval, implicit memory for the distracting words was tested using a word fragment completion task. Individuals in the positive mood group showed increased implicit memory for previously irrelevant information compared to those in the neutral mood group. These findings are consistent with the view that positive mood broadens attention to include encoding of irrelevant information in the environment, and this can impact subsequent performance.     

Ambiguous figures and the spatial contents of perceptual experience: a defense of representationalism

Representationalists hold that the phenomenal character of a perceptual experience is identical with, or supervenes on, an aspect of its representational content. As such, representationalism could be disproved by a counter-example consisting of two experiences that have the same representational content but differ in phenomenal character. In this paper, I discuss two recently proposed counter-examples to representationalism that involve ambiguous or reversible figures. I pursue two goals. My first, and most important, goal is to show that the representationalist can offer plausible responses to both counter-examples. My second goal is to show the implications of these responses for the nature of the spatial representational contents of perceptual experiences.     

Emotion-induced impairments in speeded word recognition tasks

Recent studies show that emotional stimuli impair the identification of subsequently presented, briefly flashed stimuli. In the present study, we investigated whether emotional distractors (primes) impaired target processing when presentation of the target stimulus was not impoverished. In lexical decision, animacy decision, rhyme decision, and nonword naming, targets were presented in such a manner that they were clearly visible (i.e., targets were not masked and presented until participants responded). In all tasks taboo-sexual distractors caused a slowdown in responding to the subsequent neutral target. Our results indicate that the detrimental effects of emotional distractors are not confined to paradigms in which visibility of the target is limited. Moreover, impairments were obtained even when semantic processing of stimuli was not required.     

Emotion-induced trade-offs in spatiotemporal vision

It is generally assumed that emotion facilitates human vision in order to promote adaptive responses to a potential threat in the environment. Surprisingly, we recently found that emotion in some cases impairs the perception of elementary visual features (Bocanegra & Zeelenberg, 2009b). Here, we demonstrate that emotion improves fast temporal vision at the expense of fine-grained spatial vision. We tested participants' threshold resolution with Landolt circles containing a small spatial or brief temporal discontinuity. The prior presentation of a fearful face cue, compared with a neutral face cue, impaired spatial resolution but improved temporal resolution. In addition, we show that these benefits and deficits were triggered selectively by the global configural properties of the faces, which were transmitted only through low spatial frequencies. Critically, the common locus of these opposite effects suggests a trade-off between magno- and parvocellular-type visual channels, which contradicts the common assumption that emotion invariably improves vision. We show that, rather than being a general "boost" for all visual features, affective neural circuits sacrifice the slower processing of small details for a coarser but faster visual signal.     

The disappointing gift: dispositional and situational moderators of emotional expressions

Inferences about emotions in children are limited by studies that rely on only one research method. Convergence across methods provides a stronger basis for inference by identifying method variance. This multimethod study of 116 children (mean age = 8.21 years) examined emotional displays during social exchange. Each child received a desirable gift and later an undesirable gift after performing tasks, with or without mother present. Children’s reactions were observed and coded. Children displayed more positive affect with mother present than with mother absent. Independent ratings of children by adults revealed that children lower in the personality dimension of Agreeableness displayed more negative emotion than their peers following the receipt of an undesirable gift. A curvilinear interaction between Agreeableness and mother condition predicted negative affect displays. Emotional assessment is discussed in terms of links to social exchange and the development of expressive behavior.     

Reliability and validity of the Spanish version of the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A)

The aim of this study was to determine the test-retest reliability and internal consistency of the scales of the Spanish version of the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A; Butcher et al., 1992). Two samples of 939 and 109 Spanish adolescents ages 14 to 18 years were assessed with the MMPI-A in their school environment. The first sample responded to the inventory once, whereas the second sample responded to it on 2 occasions with a 2-week interval between sessions. Results showed no significant differences in means or variances between the first and the second test administration for most MMPI-A scales. Test-retest reliability ranged between .62 (Amorality, Ma(1)) and .92 (Immaturity, IMM); most correlations exceeded .70. Internal consistency values for the MMPI-A scales in the pretest and posttest were very similar overall. External validity of the MMPI-A was demonstrated through several significant correlations between its scales and YSR/11-18 syndromes and social interaction measures. The highest correlations were established between the Anxious/Depressed YSR/11-18 scale and other MMPI-A scales such as Schizophrenia (Sc), Welsh's Anxiety (A), Adolescent-Anxiety (A-anx) and Adolescent-Alienation (A-aln), and between the Social Avoidance and Distress Scale and the MMPI-A Adolescent-Social Discomfort (A-sod) scale.
