High school athletes’ self-determined motivation: The independent and interactive effects of coach,father, and mother autonomy support

ObjectivesThe purpose of the study was to examine the independent and interactive influences of athletes’ perceptions of autonomy support from their coaches, fathers, and mothers on the athletes’ self-determined motivation.DesignCross-sectional survey.MethodHigh school athletes (N = 335; M age = 15.75 years; 62.4% female; 84.2% Caucasian) completed surveys assessing the constructs of interest near the end of their season.ResultsHierarchical regression analysis results showed that autonomy support from all three social agents significantly and positively predicted self-determined motivation (R² = 0.32), and the two- and three-way interactions significantly added to the prediction (total R² = 0.35). Results showed that a relatively high level of self-determined motivation was associated with the perception that at least two of the three social agents provided high levels of autonomy support.ConclusionsThe provision of autonomy support from coaches, mothers, and fathers relate to athletes’ self-determined motivation both independently and interactively.     

Carry-over of attentional settings between distinct tasks: A transient effect independent of top-down contextual biases

Top-down attentional settings can persist between two unrelated tasks, influencing visual attention and performance. This study investigated whether top-down contextual information in a second task could moderate this “attentional inertia” effect. Forty participants searched through letter strings arranged horizontally, vertically, or randomly and then made a judgement about road, nature, or fractal images. Eye movements were recorded to the picture search and findings showed greater horizontal search in the pictures following horizontal letter strings and narrower horizontal search following vertical letter strings, but only in the first 1000 ms. This shows a brief persistence of attentional settings, consistent with past findings. Crucially, attentional inertia did not vary according to image type. This indicates that top-down contextual biases within a scene have limited impact on the persistence of previously relevant, but now irrelevant, attentional settings.

The role of eye fixations in concentration and amplification effects during multiple object tracking

When tracking spatially extended objects in a multiple object tracking task, attention is preferentially directed to the centres of those objects (attentional concentration), and this effect becomes more pronounced as object length increases (attentional amplification). However, it is unclear whether these effects depend on differences in attentional allocation or differences in eye fixations. We addressed this question by measuring eye fixations in a dual-task paradigm that required participants to track spatially extended objects, while simultaneously detecting probes that appeared at the centres or near the endpoints of objects. Consistent with previous research, we observed concentration and amplification effects: Probes at the centres of objects were detected more readily than those near their endpoints, and this difference increased with object length. Critically, attentional concentration was observed when probes were equated for distance from fixation during free viewing, and concentration and amplification were observed without eye movements during strict fixation. We conclude that these effects reflect the prioritization of covert attention to particular spatial regions within extended objects, and we discuss the role of eye fixations during multiple object tracking.     

Quantifying the role of context in visual object recognition

An object's context may serve as a source of information for recognition when the object's image is degraded. The current study aimed to quantify this source of information. Stimuli were photographs of objects divided into quantized blocks. Participants decreased block size (increasing resolution) until identification. Critical resolution was compared across three conditions: (1) when the picture of the target object was shown in isolation, (2) in the object's contextual setting where that context was unfamiliar to the participant, and (3) where that context was familiar to the participant. A second experiment assessed the role of object familiarity without context. Results showed a profound effect of context: Participants identified objects in familiar contexts with minimal resolution. Unfamiliar contexts required higher-resolution images, but much less so than those without context. Experiment 2 found a much smaller effect of familiarity without context, suggesting that recognition in familiar contexts is primarily based on object-location memory.     

Theological Influences in Scientific Research Programs: Natural Theology “in Reverse”

The Boyle Lectures were created to promote natural theology, where science leads to belief in God. Russell's 2017 Boyle Lecture moves in the ‘opposite’ direction, showing how theological convictions held, often implicitly, by research scientists can play a creative role in both the construction of scientific theories and the choice between existing theories. As examples, Russell explores the conflicts over Big Bang versus Steady-State cosmologies, and between Einstein and Bohr about quantum mechanics. Against the claim that these influences die off once the conflict is over, Russell shows that they continue to be inherited by successive generations of scientists.     

Forced-choice and conventional personality assessment: Each may have unique value in pre-employment testing

Forced-choice (FC) personality scales are purported to predict criteria such as counterproductive work behavior (CWB) incrementally beyond conventional personality measures in pre-employment testing situations. Unfortunately, the research upon which FC tests’ claims of superiority are founded, relies upon undergraduate participants in highly artificial scenarios. Moreover, the possible predictive advantages of FC personality scales with regards to important contextual performance (CP; Borman & Motowidlo, 1993) criteria have not been investigated. We used a sample of call center employees to investigate the incremental validity of a FC personality scale over a conventional personality scale (and vice versa) with CP measures, and CWB, as criteria. Our FC and conventional personality measures were highly correlated, but each still offered unique predictive value with regards to CP or CWB. Thus, contrary to past research with student samples, in field settings FC personality scales may not be clearly superior to conventional personality scales. Moreover, contrary to widespread concern that FC measures’ predictiveness is attributable to their overlap with general mental ability, the unique predictive value of our FC measure remained even when variance due to general mental ability was statistically controlled.     

Location in negotiation: Is there a home field advantage?

Although location is considered to play an important role in negotiation potentially favoring one side over the other, little research has examined whether negotiating on one’s home field indeed confers an advantage to the resident party. We tested this possibility by experimentally manipulating participants’ occupancy status (resident versus neutral versus visitor). Across three studies, we find that residents of an office space outperform the visiting party in a distributive negotiation. In addition, our results suggest that this performance discrepancy between residents and visitors may be due to both a resident advantage (residents outperforming a neutral party) and a visitor disadvantage (visitors performing worse than a neutral party). Finally, our findings reveal that confidence partially mediates the effects of occupancy status on negotiation performance and demonstrate that an intervention designed to boost visitor confidence can help overcome the home field advantage. Implications of these results for theory and practice are discussed.     

Is flanker-based inhibition related to age? Identifying specific influences of individual differences on neurocognitive variables

Researchers frequently attempt to identify the specific neurocognitive processes that might be responsible for differences in performance associated with neurological status or other individual difference characteristics by administering two or more conditions of an experimental task to different groups of participants, and focusing on the group-by-condition interaction as the primary outcome of interest. Three limitations of this approach are discussed, and an alternative analytical method is proposed to overcome the limitations. The method is demonstrated in analyses of data from 10 cognitive tasks in two independent studies, including two flanker tasks which are often used to assess aspects of inhibition.
