Lack of habituation to shocking words: The attentional bias to their spatial origin is context free

Following a suggestion made by Aquino and Arnell (2007), we assumed that the processing of emotional words is influenced by their context of presentation. Supporting this idea, previous studies using the emotional Stroop task in its visual or auditory variant revealed different results depending on the mixed versus blocked presentation of the stimuli (Bertels, Kolinsky, Pietrons, & Morais, 2011; Richards, French, Johnson, Naparstek, & Williams, 1992). In the present study, we investigated the impact of these presentation designs on the occurrence of spatial attentional biases in a modified version of the beep-probe task (Bertels, Kolinsky, & Morais, 2010). Attentional vigilance to taboo words as well as non-spatial slowing effects of these words were observed whatever the mixed or blocked design, whereas attentional vigilance to positive words was only observed in the mixed design. Together with the results from our previous study (Bertels et al., 2010), the present data support the reliability of the effects of shocking stimuli, while vigilance to positive words would only be observed in a threatening context.     

Pitch discrimination without awareness in congenital amusia: Evidence from event-related potentials

Congenital amusia is a lifelong disorder characterized by a difficulty in perceiving and producing music despite normal intelligence and hearing. Behavioral data have indicated that it originates from a deficit in fine-grained pitch discrimination, and is expressed by the absence of a P3b event-related brain response for pitch differences smaller than a semitone and a bigger N2b–P3b brain response for large pitch differences as compared to controls. However, it is still unclear why the amusic brain overreacts to large pitch changes. Furthermore, another electrophysiological study indicates that the amusic brain can respond to changes in melodies as small as a quarter-tone, without awareness, by exhibiting a normal mismatch negativity (MMN) brain response. Here, we re-examine the event-related N2b–P3b components with the aim to clarify the cause of the larger amplitude observed by Peretz, Brattico, and Tervaniemi (2005), by experimentally matching the number of deviants presented to the controls according to the number of deviants detected by amusics. We also re-examine the MMN component as well as the N1 in an acoustical context to investigate further the pitch discrimination deficit underlying congenital amusia. In two separate conditions, namely ignore and attend, we measured the MMN, the N1, the N2b and the P3b to tones that deviated by an eight of a tone (25 cents) or whole tone (200 cents) from a repeated standard tone. The results show a normal MMN, a seemingly normal N1, a normal P3b for the 200 cents pitch deviance, and no P3b for the small 25 cents pitch differences in amusics. These results indicate that the amusic brain responds to small pitch differences at a pre-attentive level of perception, but is unable to detect consciously those same pitch deviances at a later attentive level. The results are consistent with previous MRI and fMRI studies indicating that the auditory cortex of amusic individuals is functioning normally.     

Recognition of Affective Speech Prosody and Facial Affect in Deaf Children with Unilateral Right Cochlear Implants

Cochlear implant (CI) devices provide the opportunity for children who are deaf to perceive sound by electrical stimulation of the auditory nerve, with the goal of optimizing oral communication. One part of oral communication concerns meaning, while another part concerns emotion: affective speech prosody, in the auditory domain, and facial affect, in the visual domain. It is not known whether childhood CI users can identify emotion in speech and faces, so we investigated speech prosody and facial affect in children who had been deaf from infancy and experienced CI users. METHOD: Study participants were 18 CI users (ages 7–13 years) who received right unilateral CIs and 18 age- and gender-matched controls. Emotion recognition in speech prosody and faces was measured by the Diagnostic Analysis of Nonverbal Accuracy. RESULTS: Compared to controls, children with right CIs could identify facial affect but not affective speech prosody. Age at test and time since CI activation were uncorrelated with overall outcome measures. CONCLUSION: Children with right CIs recognize emotion in faces but have limited perception of affective speech prosody.     

Development and Initial Validation of a General Psychological Well-being Scale (GPWS) in an African Context

This study aimed to develop and validate the General Psychological Well-being Scale (GPWS) in an African sample, based on the empirical overlap between hedonic and eudaimonic facets of well-being as found in previous research. The quantitative cross-sectional study was conducted in three phases: secondary data analysis (n = 2005), pilot study (n = 296) and main study (n = 459). The pilot and main study included the GPWS as well as other psychological well-being measures for criterion-related validity. The pilot study yielded satisfactory psychometric properties. The main study yielded a high, reliable Cronbach alpha of.89 and evidence of construct validity. The GPWS appears to be a unidimensional scale suitable for research use with Setswana-speaking people.     

Emotional Intelligence and the Identity Negotiation of a Racial Minority Group in a Majority School Context

This article describes the possible impact of emotional intelligence on identity negotiation of a racial minority group in a majority school context. The study investigated the adjustment and functioning of racial minority groups in majority school contexts, as well as the identity negotiation associated with it, and determined whether there is a correlation between the former and the Emotional Intelligence (EI) of the participants. Participants were 16 black and 21 white learners attending two schools where they were in the minority (mean age = 16.23 years; SD = 1.49 years). The learners attended Grades 9–12. Data were first organised, after which themes and patterns were identified, and the data appraised and categorised (Creswell, 2007), after which a comparison was drawn between the identified categories of existing knowledge. Findings suggest that racial integration in both high schools actually occurred in name only; most participants chose to mingle within their own racial groups and the black participants in particular were exposed to racism, discrimination and prejudice on a regular basis. Despite the necessary steps taken and implemented by government in order to oppose racism in the country and promote racial integration in schools, it seems that the consequences of apartheid remain for the foreseeable future.     

Measuring resilience among homeless youth: psychometric assessment of the Connor-Davidson Resilience Scale in Ghana

This study validated the psychometric structure of the Connor-Davidson Resilience Scale (CD-RISC; Connor & Davidson, 2003 Connor, K. M., & Davidson, J. R. T. (2003). Development of a New Resilience Scale: The Connor–Davidson Resilience Scale (CD-RISC). Depression and Anxiety, 18, 76–82. doi: 10.1002/da.10113[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) in a sample of 227 homeless youth in Ghana. Principal Component Analysis (PCA) with Varimax rotation was used to extract factor structures. About 62% of the total variance was accounted for by a three-factor structure: personal competence and tenacity, optimism and achievement motivation. Evidence of the external validity of scales was supported by the positive correlation between resilience and perceived social support scores. The CD-RISC appears to yield scores reliable for assessing resilience among homeless youth in a developing world context.     

Psychometric Properties of the Short Self-Regulation Questionnaire (SSRQ) in a South African Context

Self-regulation (SR), an important construct within the psychological well-being context, involves the ability to monitor behaviour, to contrast it with reference values and to introduce adjustments where necessary. A lack of validated measures of SR in the South African context has contributed to the current caveat in our knowledge of the potential importance of this construct. This investigation aimed to establish the utility of the Short Self-Regulation Questionnaire (SSRQ; Carey, Neal & Collins, 2004) in a South African context. This short version of the original Self-Regulation Questionnaire (SRQ; Brown, Miller & Lawendowski, 1999) was completed by a group of 385 undergraduate psychology students. Factor analysis produced 7 factors, all of which showed significant positive correlations with other measures of psychological well-being. This first step toward establishing the importance of SR in non-Western cultures reflected positively on the potential use of the SSRQ in large epidemiological studies.     

See an object,hear an object file: Object correspondence transcends sensory modality

An important task of perceptual processing is to parse incoming information into distinct units and to keep track of those units over time as the same, persisting representations. Within the study of visual perception, maintaining such persisting object representations is helped by “object files”—episodic representations that store (and update) information about objects' properties and track objects over time and motion via spatiotemporal information. Although object files are typically discussed as visual, here we demonstrate that object–file correspondence can be computed across sensory modalities. An object file can be initially formed with visual input and later accessed with corresponding auditory information, suggesting that object files may be able to operate at a multimodal level of perceptual processing.     

Effects on organizational context (culture and climate) from implementing a 360-degree feedback system: The case of Arcelik

The current study aims to investigate the impact of the 360-degree feedback system (DFS) on organizational context (culture and climate). This longitudinally designed study was conducted at the Arcelik Cooking Appliances Plant in Turkey with 77 white-collar workers. 360-DFS was based on relevant literature and feedback given to the employees by The Arcelik Competency Model. Results have shown that the 360-DFS has effects on organizational context (e.g., employees' perceptions regarding support and achievement culture). The results have also revealed some significant effects on the participants' perception of the communication and performance appraisal system in the organization.
