We examine neural correlates of discrete expressions of negative emotionality in infants to determine whether the microstructure of white matter tracts at 1 month of age foreshadows the expression of specific negative emotions later in infancy. Infants (n = 103) underwent neuroimaging at 1-month, and mothers reported on infant fear, sadness, and anger at 6, 12, and 18 months using the Infant Behavior Questionnaire-Revised. Levels and developmental change in fear, sadness, and anger were estimated from mother reports. Relations between MRI and infant emotion indicated that 1-month white matter microstructure was differentially associated with level and change in infant fear, but not anger or sadness, in the left stria terminalis (p < 0.05, corrected), a tract that connects frontal and tempo-parietal regions and has been implicated in emerging psychopathology in adults. More relaxed constraints on significance (p < 0.10, corrected) revealed that fear was associated with lower white matter microstructure bilaterally in the inferior portion of the stria terminalis and regions within the sagittal stratum. Results suggest the neurobehavioral uniqueness of fear as early as 1 month of age in regions that are associated with potential longer-term outcomes. This work highlights the early neural precursors of fearfulness, adding to literature explaining the psychobiological accounts of affective development.
Highlights
- Expressions of infant fear and anger, but not sadness, increase from 6 to 18 months of age.
- Early neural architecture in the stria terminalis is related to higher initial levels and increasing fear in infancy.
- After accounting for fear, anger and sadness do not appear to be associated with differences in early white matter microstructure.
- This work identifies early neural precursors of fearfulness as early as 1-month of age.

ABSTRACTThe purpose of this article is to highlight what self-care looks like for online graduate mental health counseling students and implications for counselor educators. Results come from a program evaluation examining self-care practices for online mental health graduate students. Furthermore, these results will guide the examination of best practices to meet student reported needs while integrating self-care into the program’s mission, program objectives, and curriculum. 相似文献

ABSTRACTThis study examined whether images facilitate contextual grouping as effectively as words. College students (N?=?102) read RSVP paragraphs with topics located at the beginning, middle, or end of the paragraph. Paragraph topic was presented as a topic-related image, topic-unrelated image, or written explicitly in text. Topic identification was equally accurate for topic-related images and topic sentences, and less accurate for unrelated images. Paragraphs from the text condition were recalled more accurately than the related and unrelated image conditions. Further, recognition of unrelated images was a positive predictor of the number of logical errors committed during recall. Therefore, related images did not improve memory and comprehension as much as text, and paragraphs with unrelated images negatively affected understanding of the meaning of the paragraph, but not recall. These findings have implications for multimedia information sources such as textbooks or articles that use images to clarify the meaning of the material. 相似文献

The present study compared the effects of reinforcement or punishment versus no additional consequences for instruction following on instructional control and subsequent rule-governed insensitivity. In two experiments, adult participants were presented with repeated choices between a short progressive-time schedule and either a fixed time-schedule or a longer progressive-time schedule. In Experiment 1, three groups were given an initially accurate instruction relative to the direct contingency. A control group experienced no additional consequences for compliance with instructions, whereas compliance resulted in additional points for a second group, and noncompliance led to the subtraction of points for a third group. In a subsequent phase, instructions became inaccurate and there were no additional consequences for compliance or noncompliance for any group. Consistent with previous results, rule-governed insensitivity was observed in all participants. Experiment 2 employed the same procedure, except instructions were inaccurate throughout all sessions, and compliance in the subsequent phase resulted in diminishing points per session. Reinforcement for following instructions increased instructional control and subsequent rule-governed insensitivity. This increase was maintained even after the termination of additional consequences, a result that supports theoretical suggestions that a history of reinforcement for complying with instructions and rules is an important factor in rule-governed insensitivity. 相似文献
