The Effect of Empathy on the Attentional Processing of Painful and Emotional Stimuli

The Suicide Dot Probe Task: Psychometric properties and validity in relation to suicide-related outcomes

BACKGROUND

Attentional biases to suicide-related stimuli have been linked to suicide-related outcomes. However, behavioral tasks that have been previously modified to capture suicide-specific attentional biases have demonstrated inconsistent reliability and validity. Adaptation of the Dot Probe Task, a computerized assessment that has been adapted to study a wide variety of biases, may be a promising candidate for assessing suicide-specific biases.

METHODS

In 280 recently discharged inpatients (51% male; Mage  = 40.22 years), we evaluated the psychometric properties of a modified Suicide Dot Probe Task. Participants completed this task and assessments of suicidal thoughts and behaviors at baseline and 6-month follow-up.

RESULTS

The Suicide Dot Probe Task demonstrated poor-to-moderate internal consistency and poor test-retest reliability, and participant response times were slower to suicide-specific and dysphoric stimuli than positive stimuli. However, there were no differences based on the presence or characteristics of recent or lifetime suicidal ideation or attempts. Participants' suicide-specific biases were not predictive of suicidal ideation or attempts at follow-up.

CONCLUSIONS

The Suicide Dot Probe Task exhibited questionable reliability, and differences in attentional biases were not associated with suicidal ideation or attempts. This study contributes to a body of research demonstrating the questionable utility of several behavioral tasks to study suicide-specific attentional biases.

Selective attention to pain and empathy: Studying frequent blood donors

INTRODUCTION

Empathy is an interpersonal experience that enables understanding of other's emotions and can lead to altruistic behavior such as blood donation. Cognitive theories of empathy refer to selective attention as one of its cognitive dimensions. The current study examined if individuals who engage in altruistic behavior are characterized by a distinct pattern of selective attention to observation of pain in others.

METHODS

We recruited 50 volunteer blood donors. Half (n = 25) of the volunteers donated for a self-declared altruistic reason, and the other half of the volunteers donated blood for a health-related reason. We assessed the individuals' self-reported empathy with the Interpersonal Reactivity Index (IRI). We then measured the individuals' selective attention toward faces expressing pain in a pictorial dot-probe task.

RESULTS

Consistent with the proposed hypothesis, participants who donated blood out of altruism reported significantly higher empathic concern on the IRI than those who donated blood for a health-related reason. The altruistic donors also showed significantly greater selective attention toward facial expressions of pain. Moreover, among all donors, self-report empathic concern on the IRI was significantly correlated with greater selective attention toward faces expressing pain.

DISCUSSION

These findings suggest that altruistic individuals not only show higher levels of empathy, but also attend more to the pain of others. Limitations, implications, and suggestions for future research are discussed.
