The influence of synesthesia on eye movements: no synesthetic pop-out in an oculomotor target selection task

Recent research on grapheme-colour synesthesia has focused on whether visual attention is necessary to induce a synesthetic percept. The current study investigated the influence of synesthesia on overt visual attention during an oculomotor target selection task. Chromatic and achromatic stimuli were presented with one target among distractors (e.g. a ‘2’ (target) among multiple ‘5’s (distractors)). Participants executed an eye movement to the target. Synesthetes and controls showed a comparable target selection performance across conditions and a ‘pop-out effect’ was only seen in the chromatic condition. As a pop-out effect was absent for the synesthetes in the achromatic condition, a synesthetic element appears not to elicit a synesthetic colour, even when it is the target. The synesthetic percepts are not pre-attentively available to distinguish the synesthetic target from synesthetic distractors when elements are presented in the periphery. Synesthesia appears to require full recognition to bind form and colour.     

Prime Filters, Normality and Irreducibility in Lattices

We recall some notions introduced and developed by António Aniceto Monteiro, and show how these notions have been used and generalised, thus establishing a direct and indirect influence of Monteiro??s work that extends to this day.     

The Impact of Maternal Depression and Parenting Behaviors on Adolescents' Psychological Functioning in Romania

We examined the impact of maternal depression and parenting behaviors on adolescents' psychological functioning in Romania. The direct and indirect links between maternal depression, maternal acceptance, behavioral control, psychological control and adolescent internalizing and externalizing behaviors were analyzed. The sample consisted of 239, 12–14 year-old adolescents and their mothers. Results indicated that higher maternal depression were associated with higher levels of psychological control and higher levels of internalizing and externalizing behaviors. Higher levels of behavioral control were associated with higher levels of internalizing and externalizing behaviors in adolescents.     

Economic Pressure and Children's Psychological Functioning

We examined the mediating role of family dynamics (marital quality, parental depression) in the link between economic pressure and child psychological functioning using the data from the National Survey of Family and Households (NSFH). From the initial multiethnic probability sample, we used a subsample of 2998 parents with a focal child 5 to 17 years of age. We used structural equation modeling using AMOS 4.0 to test the model. The results indicated support for associations among economic pressure, marital quality, parental depression, parenting strategies and children outcomes. Economic pressure was associated with lower marital quality and higher depression. Higher conflict and psychological distress was associated with frequent use of harsh discipline techniques and lower psychological functioning in children.     

On the syndrome of the "spare limb": one case

We describe a case of a brain-damaged patient who had a peculiar bodily illusion which could not be labelled an hallucination but seemed somatognosically and phenomenologically similar to the phantom limb without amputation. The patient, who showed left hemiplegia, felt a third upper limb (without seeing it) which he himself defined as "spare." The spare limb was not deformed; it could be moved and controlled by the patient, and there was no sensation of pain. The patient did not show psychopathological or cognitive disorders. A possible interpretation of the phenomenon is as a "phantom movement" of the paralysed limb: the mental representation of the movement of the limb was dissociated from the bodily representation of his own limb and so was still present in his consciousness despite the paralysis.     

Decoding speech prosody: do music lessons help?

Three experiments revealed that music lessons promote sensitivity to emotions conveyed by speech prosody. After hearing semantically neutral utterances spoken with emotional (i.e., happy, sad, fearful, or angry) prosody, or tone sequences that mimicked the utterances' prosody, participants identified the emotion conveyed. In Experiment 1 (n=20), musically trained adults performed better than untrained adults. In Experiment 2 (n=56), musically trained adults outperformed untrained adults at identifying sadness, fear, or neutral emotion. In Experiment 3 (n=43), 6-year-olds were tested after being randomly assigned to 1 year of keyboard, vocal, drama, or no lessons. The keyboard group performed equivalently to the drama group and better than the no-lessons group at identifying anger or fear.     

Pharmacological and physiological aspects of sexual exhaustion in male rats

The present article reviews the current findings on the interesting phenomenon of sexual satiety. Knut Larsson in 1956 reported on the development of sexual exhaustion in the male rat after repeated copulation. We have studied the process and found the following results. (1) One day after 4 hours of ad libitum copulation, two-thirds of the population showed complete inhibition of sexual behavior, while the other third displayed a single ejaculatory series from which they did not recover. (2) Several pharmacological treatments, including 8-OH-DPAT, yohimbine, naloxone and naltrexone, reverse this sexual satiety, indicating that the noradrenergic, serotonergic and opiate systems are involved in this process. Indeed, direct neurochemical determinations showed changes in various neurotransmitters during sexual exhaustion. (3) Given enough stimulation, by changing the stimulus female, sexual satiety was prevented, suggesting that there are motivational components of the sexual inhibition that characterizes sexual exhaustion. (4) The GABA antagonist bicuculline, or the electrical stimulation of the medial preoptic area, did not reverse sexual exhaustion. These data suggest, on the one hand, that sexual exhaustion and the postejaculatory interval (which is shortened by bicuculline administration) are not mediated by similar mechanisms and, on the other, that the medial preoptic area does not regulate sexual satiety. (5) The androgen receptor density in brain areas closely related to the expression of masculine sexual behavior, such as the medial preoptic nucleus, was drastically reduced in sexually exhausted animals. Such reduction was specific to certain brain areas and was not related to changes in the levels of androgens. These results suggest that changes in brain androgen receptors account for the inhibition of sexual behavior present during sexual exhaustion. (6) The recovery process of sexual satiety after 4 hours of ad libitum copulation reveals that, after 4 days, only 63% of the males are able to show sexual behavior while after 7 days all animals display copulatory activity.

Retirement Adjustment Quality: Optimism and Self-Efficacy as Antecedents of Resource Accumulation

The resource-based dynamic perspective posits that retirement adjustment quality is a direct result of an individual’s access to valuable resources during transition and in the post-retirement phase, while at the same time underscoring the need to explore the distal antecedents of adjustment quality. The present study aims to examine how distal antecedents—dispositional traits and motivational variables—influence older workers’ resource accumulation and, ultimately, how it affects retirement adjustment quality, under the resource-based dynamic perspective and Hobfoll’s resource theory. A three-wave study was designed with older Spanish workers (N = 455), who were still in active employment at time 1 and time 2 but who had retired within the last 4 months at time 3. Dispositional traits like optimism have predictive power as a gauge of resource accumulation in the short run, although not all of them were fully significant. Some unexpected findings are the limited impact of personal finances on retirement adjustment quality and the absolutely nugatory influence of cognitive resources on quality of life. The present study employs a widely validated measure of retirement adjustment quality, which should ensure comparability of findings with evidence obtained from other studies.
