Assessing two separate dimensions of interpersonal trust: Other-focused trust and propensity to trust

张明
Subjects: Psychology >> Psychological Measurement

One’s propensity to trust others and others’ trustworthiness are two important aspects of interpersonal trust. Both theory and research suggest that it is possible to distinguish between an individual’s propensity to trust (one’s ‘trustingness’ or the extent to which one feels able to trust others) and their other-focused trust (the extent to which one feels that others are worthy of our trust). However, there is as yet no measure that distinguishes between these two components of trust. In three studies, we examined the psychometrics of a proposed two-dimensional measure of trust that encompasses propensity to trust and other-focused trust components. To test discriminant validity, we also administered measures of personality, personal self-esteem, social capital, propensity to like people, perceived social support, as well as general and personal beliefs in a just world. Factor analyses supported the proposed two-factor model for the new trust measure. Further analyses supported the difference between these measures.

Multisensory Integration Inhibits Pupillary Light Reflex: Evidence from Pupil Oscillation

Multisensory integration is able to enhance stimulus saliency at the early stage of information processing hierarchy. Due to the saliency enhancement, concurrently presented audiovisual stimuli are shown to evoke a transient pupil dilation than its unisensory constituents, presumably reflecting an enhanced activation of the sympathetic pathway. Since pupil size is mediated by both the sympathetic and the parasympathetic pathways, it remains largely unknown whether multisensory integration modulates pupillary responses mediated by the parasympathetic pathway. To probe this issue, the present study measured the pupillary light reflex, which refers to the pupil constriction in response to brightness and is completely controlled by the parasympathetic pathway. We purposely evoked an oscillation of pupillary light reflex by periodically changing the luminance of the visual stimuli, and found this induced pupil oscillation was substantially attenuated when the bright but not the dark phase of a flickering stimulus was periodically and synchronously presented with a burst of tone (Experiments 1 and 2). Furthermore, the inhibited pupillary light reflex vanished when the visual stimuli were moved from the central field to the periphery (Experiment 3), while persisted when the visual stimuli appeared outside the attention focus in a demanding task (Experiment 4). These findings that multisensory integration inhibits pupillary light reflex in an eccentricity dependent but attention independent manner offer preliminary but robust evidence that the parasympathetic pathway can be modulated by multisensory integration.

Although extensive research has shown the benefits of meditation on attention, evidence for the benefits of short-term meditation training remains scarce. In addition, prior studies on these benefits have included considerably more females than males, potentially concealing gender differences in attention training effects. Here we present a longitudinal study including equal-sample male and female participants to explore potential gender differences in short-term meditation training effects on an attentional blink (AB) task. One hundred and sixty-five college students were randomly divided into three groups: meditation training, video game training and control (no training). Participants were asked to complete the Five-Facet Mindfulness Questionnaire and the State-Trait Anxiety Inventory, and to rate their level of emotional state and time spent on video game playing per day. Participants then completed a 4-day, 20-min training including meditation training, video game training, or a waiting period (control). After training, participants rated their arousal state and emotional state, and performed the AB task. Results showed that participants who completed either short-term meditation training or video game training showed significant improvement on AB performance. Interestingly, meditation training was more effective in females, while video game training was more effective in males. Meditation training, but not video game training, decreased anxiety scores. The current results indicate that gender plays an important role in the benefits of attention training. It is essential that clinicians take gender into consideration when implementing meditation based therapy.
