The Impact of Race and Inclusionary Status on Memory for Ingroup and Outgroup Faces

We explore how rejection by racial ingroup or outgroup members influences the Other Race Effect (ORE; the tendency to have better memory for same-race [SR] relative to other-race [OR] faces). White and Black participants were rejected or accepted by two racial ingroup or outgroup members during an online game. Participants then completed a face recognition task assessing SR and OR targets. Those playing with ingroup members showed the classic ORE. However, inclusion by outgroup members led to the ORE, while exclusion by outgroup members eliminated this effect by increasing outgroup face memory. We discuss future work on exclusion and the ORE.     

Does Motivational Interviewing (MI) Work With Nonaddicted Clients? A Controlled Study Measuring the Effects of a Brief Training in MI on Client Outcomes

This study investigated the relationships between motivational interviewing (MI) and client symptoms, attendance, and satisfaction. Seventy‐nine clients attending a university‐based counseling center were purposefully assigned to treatment or control conditions. Statistical analyses revealed client symptoms in both groups improved. However, clients assigned to treatment conditions attended more sessions and missed fewer sessions than clients in the control group. Implications for using MI and suggestions for additional research are explored within the study.     

Is Person–Organization Fit Beneficial for Employee Creativity? Moderating Roles of Leader–Member and Team–Member Exchange Quality

ABSTRACT

This study investigates the effect of person–organization (PO) fit on employee creativity. We draw on social exchange theory and identify leader–member exchange (LMX) and team–member exchange (TMX) as moderating contingencies. Our empirical analysis based on 167 employee–supervisor dyads confirms that LMX activates the significance of PO fit toward creativity. In addition, under high LMX, PO fit effect on creativity is positive when TMX is high. Subsequent analyses show that employees with high PO fit exhibit the highest level of creativity when LMX and TMX are high. Findings on the three-way interaction among PO fit, LMX, and TMX toward creativity offer new insights into a phenomenon that is mostly neglected in the literature.     

Cue competition effects in the planarian

The learning abilities of planarian worms (Dugesia tigrina) were assessed by using a number of Pavlovian conditioning paradigms. Experiment 1 showed that planaria were susceptible to basic conditioning in that they readily developed a conditioned response to a change in ambient luminance when it was consistently paired with an electric shock over a number of trials. In Experiment 2, the change in luminance was presented in a compound with a vibration stimulus during conditioning. Subsequent tests revealed poor conditioning of the elements compared with control groups in which the animals were conditioned in the presence of the elements alone, an instance of overshadowing. In Experiment 3, pre-training of one of the elements before compound conditioning resulted in blocking of learning about the other element. These results add to other studies that have reported cue competition effects in animal species belonging to different phyla (chordate, mollusk, arthropod), suggesting that learning in these phyla could be ruled by similar principles. The results are discussed adopting an evolutionary-comparative approach.     

Burnout and its relations with basic psychological needs and motivation among athletes: A systematic review and meta-analysis

ObjectivesThe present study is a review on studies about the relationships between the three basic psychological needs/motivational regulations (i.e., amotivation, controlled regulation, extrinsic autonomous regulation, and intrinsic motivation) and burnout.DesignA systematic review and meta-analysis.MethodStudies were identified through five electronic databases and manual search using combinations of three groups of keywords. Three inclusion criteria were then used to screen the searched articles.ResultsEighteen studies met the inclusion criteria and these studies varied considerably in terms of their study characteristics (e.g., characteristics of participants, study designs, and outcome measures). The results also showed that the three basic psychological needs, intrinsic motivation, extrinsic autonomous regulation, and amotivation had small to large effects on predicting global burnout and its three dimensions. However, controlled regulation showed no or weak correlations with the burnout subscales.ConclusionsSelf-determination theory was generally supported in explaining athlete burnout.     

The Blood of Jesus in revival theology and the contemporary Church with particular reference to the East African Revival and Roy Hession

One of the most common phrases heard in testimony, preaching, and song during the East African Revival (EAR) was the phrase ‘The Blood of Jesus Christ’. Taken from a rich biblical heritage, this phrase encapsulates a wide range of ideas concerning the work of the cross and the power of forgiveness in a believer's life. Whilst, as will be noted, the use of The Blood has been common to many revivals, this article examines especially the theology behind this phrase by looking at the most prominent of the EAR authors – Roy Hession. It investigates seven different applications of The Blood in a believer's life: The Blood as a testament that sin is forgiven, The Blood as cleansing the conscience, The Blood as victory over despair, The Blood as the remover of shame, The Blood as washing away sin, The Blood as the gateway of the Holy Spirit, and finally The Blood as the source of true fellowship. The theology of The Blood has a long history of use in the Church but it also comes with difficulties. To this end the article will investigate the legitimacy of the practice often found in Africa and some Pentecostal circles of invoking The Blood as protection against the demonic. The article closes by considering the reasons why speaking of The Blood in church can be uncomfortable yet is paradoxically of vital importance to revival.     

Objective assessment of the functional role of spike train correlations using information measures

The functional role of correlations between neuronal spike trains remains strongly debated. This debate partly stems from the lack of a standardized analysis technique capable of accurately quantifying the role of correlations in stimulus encoding. We believe that information theoretic measures may represent an objective method for analysing the functional role of neuronal correlations. Here we show that information analysis of pairs of spike trains allows the information content present in the firing rate to be disambiguated from any extra information that may be present in the temporal relationships of the two spike trains. We validate and illustrate the method by applying it to simulated data with variable degrees of known synchrony, and by applying it to recordings from pairs of sites in the primary visual cortex of anaesthetized cats. We discuss the importance of information theoretic analysis in elucidating the neuronal mechanisms underlying object identification.     

Effects of varying target luminance and cue luminance on attentional effects of spatial cues

Attentional effects of letter cues on target processing were investigated in a bilateral spatial cueing paradigm. Luminance contrast of the cue stimuli and of the target stimuli were both manipulated. Consistent with predictions derived from theoretical models of visual attention, manipulating cue luminance and target luminance had very different effects on performance. In agreement with the dorsal stream attention hypothesis (Marrett et al., 2011) orienting effects were unaffected by changes in cue luminance; but in agreement with the work of Reynolds, Pasternak, and Desimone (2000) and Carrasco, Ling, and Read (2004) orienting effects were strongly modulated by changes in the luminance and perceptual quality of the target. Theoretical implications of the results are considered and the data are explained in terms of a sensory enhancement effect, whereby attention amplifies the neuronal responses for attended stimuli.
