The Relationship

A 2 (trait anxiety) × 4 (color) factorial design was used to determine the effects of red, green, yellow, and blue on state anxiety as a function of high and low trait anxiety. The State-Trait Anxiety Inventory was used to assess both trait (A-Trait) and state (A-State) anxiety for the 10 students assigned to each of the eight treatment combinations. High A-Trait students were significantly more anxious while viewing blue, red, and green than were the low A-Trait students and blue produced significantly more state anxiety than did either yellow or green. These results are consistent with state-trait theory and indicate that the effects of color on state anxiety may be confounded with trait anxiety unless the levels of A-Trait are equivalent for each color condition. The role of cultural and individual differences in the relationship between color and emotion and implications for research are discussed.

Dichhaptic perception of nonsense forms was examined in familial righthanders. In Exp. 1, 15 males and 15 females performed similarly, obtaining a non-significant right-hand superiority with a 5-sec. memory interval between presentation of stimuli and their choice-recognition response. Individual differences in Block Design scaled scores but not State or Trait anxiety were related to hand performance for both sexes. One strategy on a questionnaire was related to performance of males. Exp. 2 was a replication with the memory interval removed. A significant right-hand superiority was obtained and different strategies were related to performance of males and females.

Study Participants

AbstractFaces transmit rich information about a unique personal identity. Recent studies examined how negative evaluative information affects event-related potentials (ERPs), the relevance of individual differences, such as trait anxiety, neuroticism, or agreeableness, for these effects is unclear. In this preregistered study, participants (N = 80) were presented with neutral faces, either associated with highly negative or neutral biographical information. Faces were shown under three different task conditions that varied the attentional focus on face-unrelated features, perceptual face information, or emotional information. Results showed a task-independent increase of the N170 component for faces associated with negative information, while interactions occurred for the Early Posterior Negativity (EPN) and the Late Positive Potential (LPP), showing ERP differences only when paying attention to the evaluative information. Trait anxiety and neuroticism did not influence ERP differences. Low agreeableness increased EPN differences during perceptual distraction. Thus, we observed that low agreeableness leads to early increased processing of potentially hostile faces, although participants were required to attend to a face-unrelated feature.

Threat Of Shock

A well documented amygdala-dorsomedial prefrontal circuit is theorized to promote attention to threat (‘threat vigilance’). Prior research has implicated a relationship between individual differences in trait anxiety/vigilance, engagement of this circuitry, and anxiogenic features of the environment (e.g. through threat-of-shock and movie-watching). In the present study, we predicted that—for those scoring high in self-reported anxiety and a behavioral measure of threat vigilance—this circuitry is chronically engaged, even in the absence of anxiogenic stimuli. Our analyses of resting-state fMRI data (N=639) did not, however, provide evidence for such a relationship. Nevertheless, in our planned exploratory analyses, we saw a relationship between threat vigilance behavior (but not self-reported anxiety) and intrinsic amygdala-periaqueductal gray connectivity. Here, we suggest this subcortical circuitry may be chronically engaged in hypervigilant individuals, but that the amygdala-prefrontal circuitry may only be engaged in response to anxiogenic stimuli.

Emotional Harm

Imaginative resistance refers to cases in which one’s otherwise flexible imaginative capacity is constrained by an unwillingness or inability to imaginatively engage with a given claim. In three studies, we explored which imaginative demands engender resistance when imagining morally deviant worlds and whether individual differences in emotion predict the degree of this resistance. Participants read narratives containing either no harmful actions, harmful actions, or harmful actions with evaluative statements that the harms were morally justified, after which measures of moral judgment and imaginative resistance were assessed. In Study 1 (N = 176), participants resisted the notion that harmful actions could be morally acceptable regardless of the author’s claims about these actions but did not resist imagining that a perpetrator of harm could believe their actions to be morally acceptable. In Study 2 (N = 167) we replicated the findings of Study 1 and showed that imaginative resistance is greatest among participants who experience more negative affect in response to imagining harm and are lower in either trait anxiety or trait psychopathy. In Study 3 (N = 210) we show that this is the case even when the harms assessed include both low-severity (i.e., emotional harm) and high-severity (i.e., killing) cases. These findings suggest that people’s moral beliefs constrain their ability to imagine hypothetical moral alternatives, although this ability systematically varies on the basis of stable individual differences in emotion.

The present study explored emotional thinking in the adult using four related scales. A new Mysticism Scale assessed tendencies to use magical, esoteric, incomprehensible, and unfounded concepts and hypotheses. Two related scales (Paranormal Belief, Magical Ideation) correlated .88 and .74, respectively, with the Mysticism Scale. The Globality-Differentiation Scale assessed emotional, subjective, and centered thinking and related to unpleasant, arousable, and submissive characteristics, showing it to be the cognitive counterpart of Trait Anxiety or Neuroticism. The Globality/maladjustment relationship was confirmed by positive relationships of the Globality Scale with measures of Trait Anxiety, Depression, Panic, Somatization, and Drug Use. In comparison, the Mysticism Scale related only to Trait Arousability (a measure of positive and/or negative emotional sensitivity) and, along with the Paranormal Belief and Magical Ideation scales, was generally unrelated to measures of psychopathology.
