Gender differences in awareness of courtship initiation tactics

In this study, two phases of the initiation of courtship behavior are distinguished, namely the first move of making the contact, and the self-presentation after the contact has been established. Gender differences with respect to cognitions and expectations of courtship behavior were analyzed through self-report in a Dutch Caucasian student population. Our goal was to assess male and female roles in these two phases, and to relate the findings to hypothesized gender role changes. It appeared that both men and women were apparently unaware of which gender usually initiates courtship. Furthermore, both genders reported eye contact as the most frequently used initiation tactic. However, the genders differed in other tactics, women reporting the use of indirect nonverbal tactics more often than men, and men reporting their engagement in direct verbal ones more often than women. In presenting themselves, men stressed personal characteristics that are traditionally interpreted as female-valued (such as tenderness) more than women did, whereas women stressed characteristics that are traditionally interpreted as male-valued (such as being prestigiously occupied) more than men did. This apparent change in gender role pattern is discussed against the background of the assumed function of courtship behavior and societal developments.     

The effects of spatial phase on reaction time to spatially filtered images

Summary Many studies of visual perception have used periodic stimuli such as sine-wave gratings and checker-board patterns. It is well known that reaction time (RT) to such stimuli increases with increasing spatial frequency and decreasing contrast. While this is the case with periodic stimuli it is not clear that these relationships obtain for aperiodic stimuli such as natural scenes. A digitized image of an object (a vase) was submitted to two-dimensional Fourier analysis. Four pairs of spatial frequency band-limited images were created for each image. Each pair consisted of a normal-phase (NP) and a scrambled-phase (SP) version, with the magnitude spectrum and space-averaged luminance the same within each pair. Filter band-widths were 1 octave wide. Manual RT was measured for onset and offset of each spatially filtered image. Mean RT for SP images increased significantly with increasing spatial frequency, while no other significant differences were found with the NP images. This suggests that the temporal processing of complex, aperiodic images is influenced by the spatial frequency and contrast of local regions within the image, rather than by the space-averaged contrast of the entire image, and cannot be predicted by global estimates of contrast and spatial frequency.     

Enhancing Initial Parental Engagement in Interventions for Parents of Young Children: A Systematic Review of Experimental Studies

Low rates of participation in parenting interventions may undermine their effectiveness. Although a wide range of strategies to engage parents in interventions are described in the literature, little is known about which engagement strategies are most effective in enhancing parental engagement. This systematic review explores effective engagement strategies to encourage initial parental engagement (recruitment, enrolment, and first attendance) in parenting interventions for parents of children aged 2–8 years old. This review was conducted based on the guidelines of the Cochrane Handbook for Systematic Reviews of Interventions (Higgins and Green 2011) and the Preferred Reporting Items for Systematic Review and Meta-Analysis (Moher et al. 2009). Electronic systematic searches from January 1996 to August 2017 were conducted in PsycINFO, Scopus, ProQuest Social Sciences Journals, CINAHL, and PubMed databases. Eight studies met the inclusion criteria representing 1952 parents from four different countries. Of the engagement strategies tested in included studies (monetary incentive, setting, testimonial, advertisement, and engagement package), three strategies (advertisement, incentive, and engagement package) showed a significant effect on a stage of engagement, but none across stages. The low methodological quality of the selected studies limits their generalisability and thus provides limited evidence regarding effective engagement strategies to increase recruitment, enrolment, and first attendance rates in parenting interventions. There is a need for further, more methodologically rigorous, research evidence regarding how to engage parents more effectively in the early stages of parenting interventions.     

Poststimulation time interval-dependent effects of motor cortex anodal tDCS on reaction-time task performance

Anodal transcranial direct current stimulation (tDCS) induces long-term potentiation-like plasticity, which is associated with long-lasting effects on different cognitive, emotional, and motor performances. Specifically, tDCS applied over the motor cortex is considered to improve reaction time in simple and complex tasks. The timing of tDCS relative to task performance could determine the efficacy of tDCS to modulate performance. The aim of this study was to compare the effects of a single session of anodal tDCS (1.5 mA, for 15 min) applied over the left primary motor cortex (M1) versus sham stimulation on performance of a go/no-go simple reaction-time task carried out at three different time points after tDCS—namely, 0, 30, or 60 min after stimulation. Performance zero min after anodal tDCS was improved during the whole course of the task. Performance 30 min after anodal tDCS was improved only in the last block of the reaction-time task. Performance 60 min after anodal tDCS was not significantly different throughout the entire task. These findings suggest that the motor cortex excitability changes induced by tDCS can improve motor responses, and these effects critically depend on the time interval between stimulation and task performance.     

Organizational justice and extrarole customer service: The mediating role of well-being at work

The purpose of this article is to propose and test a model of extrarole customer service (ERCS). We propose that organizational justice (distributive, procedural, interpersonal, and informational) promotes well-being at work (low burnout and high engagement). Well-being at work, in turn, engenders more effective ERCS. Thus, well-being at work is considered a mediator of the relationships from organizational justice to ERCS. This fully mediated model was compared to an alternative fully direct model. The sample consisted of 317 contact employees who were working in the Spanish service sector. The results of structural equation modelling supported the importance of the mediating role of the positive side of well-being at work (engagement) in the relationship between organizational justice and ERCS. The article concludes with a discussion of the theoretical and managerial implications.

Effects of manipulating valence and arousal components of mood on specificity of autobiographical memory

An important cognitive deficit in clinical depression is the inability to be specific in recalling personal memories, a phenomenon coined "overgeneral memory" by Williams and Broadbent. Although there is general consensus that overgeneral memory is not state-dependent, most of the evidence originates from studies of this effect in clinical populations. The two components of mood, valence and arousal, were manipulated to examine their influence on memory specificity in a nonclinical sample of university undergraduate students. In Exp. 1, a Velten procedure was used to induce elated, depressed, or neutral mood states. No difference was found in autobiographical memory specificity among the three groups. In Exp. 2, high and low arousal states were induced through physical exercise. A low arousal state resulted in an increased proportion of overgeneral memories, suggesting that this memory phenomenon may be influenced by the arousal component of mood.     

Individual characteristics and career exploration in adolescence

The effects of gender, age and school grade on several career exploration dimensions measured by the Career Exploration Survey were investigated. Subjects were high school students facing an imminent career decision. Regression analyses indicated that sex and grade-level were the most significant and prevailing individual characteristics related to the adolescents' career exploration behaviours, reactions and beliefs. Implications for career exploration interventions are discussed.
