Technological Limitations

The use of the unecological removal research scenario in recent years has been forced because of technological limitations. However, with the advent of three-dimensional modeling programs and high-fidelity graphic systems, the ability to accurately represent real-world situations in computer-generated worlds has become easier, cheaper, and more realistic. A time-to-contact (TTC) experiment is reported in which the manner of removing an approaching vehicle from the environment was manipulated. One scenario, the disappearance condition, featured a traditional, instantaneous removal of a vehicle. The purpose of this research was to determine if a more ecological research scenario, one in which the approaching vehicle becomes occluded by a naturally occurring object (the occlusion condition), influences a driver’s ability to estimate TTC accurately. The available visual information was essentially equivalent in both scenarios. If the level of ecological validity has no effect on estimates of TTC, estimates of TTC between the two scenarios would be expected to be similar. Results, however, showed estimates with 14 percent greater accuracy in the occlusion condition compared with the disappearance condition, implying that researchers have been using a research scenario that biases estimates of TTC. Further, the results of the present findings imply that there are processes that occur in real world settings that have not being accounted for in previous TTC research.

The Impact

Revealing the functioning of non-standard visual systems such as compound eyes is of interest to biologists and engineers alike. A key investigative method is to replicate the sensory apparatus using artificial systems, allowing for investigation of the visual information that drives animal behaviour when exposed to environmental cues. To date, 'Compound Eye Models' (CEMs) have largely explored the impact of features such as spectral sensitivity, field of view, and angular resolution on behaviour. Yet, the role of shape and overall structure have been largely overlooked due to modelling complexity. However, modern real-time raytracing technologies are enabling the construction of a new generation of computationally fast, high-fidelity CEMs. This work introduces new open-source CEM software (CompoundRay) alongside standardised usage techniques, while also discussing the difficulties inherent with visual data display and analysis of compound eye perceptual data. CompoundRay is capable of accurately rendering the visual perspective of a desert ant at over 5,000 frames per second in a 3D mapped natural environment. It supports ommatidial arrangements at arbitrary positions with per-ommatidial heterogeneity.

Collectivist Cultures

The degree of individualism or collectivism in a culture has observable effects on cognitive processing. Participants from collectivist cultures are less able to identify a previously displayed object when presented with a novel background than participants from individualist cultures. This can be interpreted as collectivist cultures more likely to process information field dependently. We tested explicitly whether collectivist or individualist cultures are more likely to bind foreground and background images and whether such binding is differentially affected for object-scene and action-scene combinations. Across three experiments participants viewed item-context composites, then completed a forced-choice recognition task. In Experiment 1, 61 UK and 57 Malaysian participants viewed object-scene composites, with UK participants significantly more accurate in correct composite recognition, with Experiment 2 demonstrating this difference was not due to cultural differences in object familiarity. In Experiment 3, 62 UK and 67 Malaysian participants viewed action-scene composites, with no significant difference between cultures in proportion of items recognised. The results of Experiment 1 suggest that the UK sample were able to store high-fidelity representations of visual features as an association between item and context, while the Malaysian sample were unable to. This result is discussed in relation to both cultural, and cognitive psychology.

Thirty infants, ranging in age from 4 to 11 months, were tested with five different recorded sounds that varied in bandwidth and temporal configuration: a continuous band of white noise, the same band of noise interrupted twice per second, the crinkling of onionskin paper, a narrow band of noise centered at 3000 Hz, and a warbled 3000 Hz tone. With loudness and duration of the stimuli held constant, more responses occurred to sounds composed of a broadband spectrum than to those of a limited bandwidth. Temporal configuration of the sound had no effect on the number of responses elicited.

The multimodal nature of human communication has been well established. Yet few empirical studies have systematically examined the widely held belief that this form of perception is facilitated in comparison to unimodal or bimodal perception. In the current experiment we first explored the processing of unimodally presented facial expressions. Furthermore, auditory (prosodic and/or lexical-semantic) information was presented together with the visual information to investigate the processing of bimodal (facial and prosodic cues) and multimodal (facial, lexic, and prosodic cues) human communication. Participants engaged in an identity identification task, while event-related potentials (ERPs) were being recorded to examine early processing mechanisms as reflected in the P200 and N300 component. While the former component has repeatedly been linked to physical property stimulus processing, the latter has been linked to more evaluative “meaning-related” processing. A direct relationship between P200 and N300 amplitude and the number of information channels present was found. The multimodal-channel condition elicited the smallest amplitude in the P200 and N300 components, followed by an increased amplitude in each component for the bimodal-channel condition. The largest amplitude was observed for the unimodal condition. These data suggest that multimodal information induces clear facilitation in comparison to unimodal or bimodal information. The advantage of multimodal perception as reflected in the P200 and N300 components may thus reflect one of the mechanisms allowing for fast and accurate information processing in human communication.

Abstract. Faking has been a concern in selection research for many years. Many studies have examined faking in questionnaires while far less is known about faking in selection exercises with higher fidelity. This study applies the theory of planned behavior (TPB; Ajzen, 1991 ) to low- (interviews) and high-fidelity (role play, group discussion) exercises, testing whether the TPB predicts reported faking behavior. Data from a mock selection procedure suggests that candidates do report to fake in low- and high-fidelity exercises. Additionally, the TPB showed good predictive validity for faking in a low-fidelity exercise, yet not for faking in high-fidelity exercises.

This study investigates how multitasking interacts with levels of sexually explicit content to influence an individual’s ability to recognize TV content. A 2 (multitasking vs. nonmultitasking) by 3 (low, medium, and high sexual content) between-subjects experiment was conducted. The analyses revealed that multitasking not only impaired task performance, but also decreased TV recognition. An inverted-U relationship between degree of sexually explicit content and recognition of TV content was found, but only when subjects were multitasking. In addition, multitasking interfered with subjects’ ability to recognize audio information more than their ability to recognize visual information.
