Relating numeric cognition and language processing: Do numbers and words share a common representational platform?

Numerical processing and language processing are both grounded in space. In the present study we investigated whether these are fully independent phenomena, or whether they share a common basis. If number processing activates spatial dimensions that are also relevant for understanding words, then we can expect that processing numbers may influence subsequent lexical access to words. Specifically, if high numbers relate to upper space, then they can be expected to facilitate understanding of words such as bird that are having referents typically found in the upper vertical space. The opposite should hold for low numbers. These should facilitate the understanding of words such as ground referring to entities with referents in the lower vertical space. Indeed, in two experiments we found evidence for such an interaction between number and word processing. By eliminating a contribution of linguistic factors gained from additional investigations on large text corpora, this strongly suggests that understanding numbers and language is based on similar modal representations in the brain. The implications of these findings for a broader perspective on grounded cognition will be discussed.     

Discrimination of two neighboring intra- and intermodal empty time intervals marked by three successive stimuli

We investigated the discrimination of two neighboring intra- or inter-modal empty time intervals marked by three successive stimuli. Each of the three markers was a flash (visual—V) or a sound (auditory—A). The first and last markers were of the same modality, while the second one was either A or V, resulting in four conditions: VVV, VAV, AVA and AAA. Participants judged whether the second interval, whose duration was systematically varied, was shorter or longer than the 500-ms first interval. Compared with VVV and AAA, discrimination was impaired with VAV, but not so much with AVA (in Experiment 1). Whereas VAV and AVA consisted of the same set of single intermodal intervals (VA and AV), discrimination was impaired in the VAV compared to the AVA condition. This difference between VAV and AVA could not be attributed to the participants' strategy to perform the discrimination task, e.g., ignoring the standard interval or replacing the visual stimuli with sounds in their mind (in Experiment 2). These results are discussed in terms of sequential grouping according to sensory similarity.     

Sequential aiming with one and two limbs: Effects of target size

It is well reported that movement times to the first target in a two-target sequence are slower than when a single target response is required. This one-target advantage has been shown to emerge when the two-target sequence is performed with the same limb and when the first and second segments within the sequence are performed with different limbs (i.e., when there is a switch between limbs at the first target). The present study examined the functional dependency between response segments in both single and two limb sequential aiming by varying the accuracy demands at the first and second target. Results revealed that, for both one and two limb conditions, the one-target advantage was present with large first targets but not with small first targets. Additionally, when the first target was large and the second target was small, spatial variability at the first target was significantly less (or constrained more) in both one and two limb conditions compared to conditions requiring only a single target response. These findings suggest that similar principles underlie the one-target advantage in both single and two limb sequential movements.     

Intentional Binding is independent of the validity of the action effect's identity

When an action produces an effect, both events are perceived to be shifted in time toward each other. This shift is called Intentional Binding (IB) effect. First evidence shows that this shift does not depend on the statistical predictability of the produced effect's identity (Desantis, Hughes, & Waszak, 2012). We confirm this result by comparing the perceived duration of action–effect intervals before valid and invalid action effects using the method of constant stimuli. The perceived duration of action–effect intervals did not differ for valid and invalid effects. This result was true for different durations of the action–effect interval (Experiments 1–4: 250 ms, Experiments 1 & 2: 400 ms), different effect modalities (Experiments 1 & 3: visual, Experiments 2–4: auditive), and two types of validity variations (Experiments 1 & 2: 80% valid, Experiments 3 & 4: 100% valid vs. random). We validated our results by using a clock paradigm and a numerical duration estimation task (Experiment 4). We conclude that the IB effect is not the result of internal prediction due to action–effect bindings, but might rely on higher-order processes.     

L’influence longitudinale de la justice organisationnelle sur le bien-être psychologique au travail : quels types de justice sont déterminants ?

Regarding the relationship between perceived organizational justice and psychological well-being at work, few studies compare the influence of the four organizational justice facets, and even fewer do so longitudinally. The objective of this study is to evaluate the longitudinal relationships between these facets and psychological well-being at work. Social exchange theory suggests that distributive, interpersonal, and informational justices are better predictors of well-being than procedural justice. A sample of 192 Canadian workers from a diversity of occupations completed two self-reported questionnaires at a six-month interval. Results support the importance of rewards allocation (distributive justice) and information given on this allocation (informational justice) to promote workers’ well-being.     

Implications for Wellness‐Based Supervision and Professional Quality of Life

This study evaluated the efficacy of the wellness model of supervision (WELMS; Lenz & Smith, 2010 ) for promoting changes across the perceptions of counselors‐in‐training (CITs) regarding professional quality of life. Three female participants (1 Caucasian, 2 Hispanic) were enrolled in a program accredited by the Council for Accreditation of Counseling and Related Educational Programs. Results of a single‐case research design with multiple baselines indicated that the WELMS was efficacious across client–CIT interactions on professional quality of life.     

Sexual willingness with same- and other-sex prospective partners: Experimental evidence from the bar scene

Sex is ubiquitous in the media, but only a fraction depicts sexual interactions between same-sex partners. This field study, conducted outside of bars in the Midwestern United States, examined 83 heterosexuals’ sexual willingness with a same- or other-sex partner. Participants viewed a randomly assigned video vignette of a same- or other-sex partner. Alcohol intake, partner attractiveness, and sexual willingness were measured. Using moderated regression analysis, we found that alcohol intake predicted sexual willingness with the male target for both men and women, but not with the female target. The attractiveness of same-sex partners was related to sexual willingness. Sexual willingness was only influenced by alcohol intake and perceived attractiveness of a same-sex prospective partner. Most notably, alcohol intake was related to increased sexual willingness of men with a same-sex partner, suggesting a potential shift in normative casual sexual behavior among heterosexual men.     

Parent management training for conduct problems in children: Enhancing treatment to improve therapeutic changeCapacitación en entrenamiento de padres para problemas de conducta en niños: mejorar el tratamiento para mejorar el cambio terapéutico

Background/Objective: The study evaluated two variations of Parent Management Training (PMT) for children referred to treatment for oppositional, aggressive, and antisocial behavior. The goal was to evaluate the impact of multiple enhancements to optimize common and placebo factors to augment therapeutic change. Method: The families of all children (N=138, 39 girls and 99 boys, ages 6-13) received PMT. One half of the families were assigned to receive an enhanced version with multiple additions designed to increase bonding of the parent to the therapist, professionalism of treatment and setting, credibility of the intervention, and expectancies for therapeutic change. Assessment included multiple treatment outcome measures of the child (problem behaviors, psychiatric symptoms, social competence, and adaptive functioning) and parents (depression, stress, and family relations) showed marked improvements over the course of treatment, and several process measures (therapeutic alliance, credibility of the procedures, expectancy for change). Results: The results indicated that children and parents made marked improvement in all the treatment outcome measures. The vast majority of children fell within the normative range at posttreatment on problem and prosocial behaviors. The two treatment conditions were no different in outcomes for children or parents. Conclusion: PMT led to marked changes in treatment outcome.     

Consensual Assessment of Creativity in Teaching Design by Supportive Peers—Its Validity,Practicality, and Benefit

Creativity in teaching is a significant and complex construct. However, in the local educational context, creativity in teaching has received little attention. This study aimed to investigate the validity, practicality, and benefits of applying a modified consensual assessment technique (CAT) to assess creativity in teaching design. Four hundred and eighty‐five written teaching designs were collected from 167 in‐service and pre‐service primary school teachers in Hong Kong. Instead of expert teachers, “supportive” peers, who had shown support, interest, and initiative in creative teaching were recruited as judges. A warm‐up exercise, with no definition of creativity, was given to the judges before beginning their assessments. The results indicated overall consistency in the judges' assessments of creativity, and that creativity factor could be distinguished from pedagogical skills and other technical factors. Most of the peer judges reported personal gains in creative teaching by engaging in the assessment process. On average, each judge spent approximately only 2 minutes rating each written teaching design. The findings confirm that the modified CAT is a valid and economical assessment method with learning benefits for the judges. The special values and implications of using supportive peer judges in consensual assessment are further discussed.
