Criterion Validity of the Implicit Positive and Negative Affect Test: Prediction of Facial Affect Perception

This study focused on the criterion-related validity of the Implicit Positive and Negative Affect Test (IPANAT). The IPANAT is thought to be a measure of automatic activation of cognitive representations of affects. In this study, it was investigated whether implicit affect scores differentially predict ratings of facial emotions over and above explicit affectivity. Ninety-six young female participants completed the IPANAT, the Positive and Negative Affect Schedule (PANAS) as an explicit measure of state and trait affectivity, and a task for the perception of facial emotions. Implicit negative affect predicted the perception of negative but not positive facial emotions, whereas implicit positive affect predicted the perception of positive but not negative facial emotions. The observed double-dissociation in the correlational pattern strongly supports the validity of the IPANAT as a measure of implicit affectivity and is indicative of the orthogonality and thus functional distinctness of the two affect dimensions of the IPANAT. Moreover, such affect-congruent correlations were absent for explicit affect scales, which additionally supports the incremental validity of the IPANAT.

Existential Threat: Uncovering Implicit Affect in Response to Terror Reminders in Soldiers

Psychological science has a hard time assessing affective processes of the individuals that they may not recognize or do not like to report on. Here, the authors used the Implicit Positive and Negative Affect Test (IPANAT; Quirin et al., 2009) to investigate whether reminders of an existential threat induce unpleasant implicit affect in soldiers waiting for their deployment to a country with high levels of terrorist threat, Afghanistan. As expected, relative to reminding participants of a television evening, implicit negative affect was higher and implicit positive affect was lower after reminding participants of terror acts performed in different cities. No significant effects were found in self-reports of negative or positive affect. Our findings suggest that reminders of existential threat can elicit implicit negative affect that individuals may not report on explicitly and thus, validate the IPANAT as an easily applicable measure in emotional contexts.

Implicit affectivity in clinically depressed patients during acute illness and recovery

Background Clinical depression is characterized by high levels of negative affect (NA) and attenuated positive affect (PA). Psychological and pharmacological treatments have been shown to reduce NA and to enhance PA in depressed patients. Following dual-process models, two types of affect can be distinguished: explicit (or self-reported) affect, which is formed by conscious reflections, and implicit affect, which relates to automatic affective reactions. The present study was conducted to examine, for the first time, both implicit and explicit affectivity in patients suffering from acute depression. Moreover, changes in patients’ implicit and explicit affectivity were investigated over the course of inpatient treatment. Methods Thirty-nine patients suffering from major depression and 39 healthy individuals participated in the study. Implicit affectivity was assessed using the Implicit Positive and Negative Affect Test. The explicit state and trait affectivity were measured by the Positive and Negative Affect Schedule. The level of depressive symptoms was assessed with the Beck Depression Inventory. Tests were administered to patients after admission and after 7 weeks of therapy, whereas healthy controls were investigated only once. We examined whether either comorbidity or antidepressant medication has an effect on affectivity. Results Patients with acute depression had lower implicit and explicit PA scores and higher implicit and explicit NA scores than the healthy controls. After treatment, patients’ level of depression decreased significantly. At posttreatment, patients exhibited heightened implicit and explicit PA and diminished explicit trait NA. Independent of antidepressant medication and comorbidity, no significant change in implicit NA was observed over the course of treatment. Implicit NA was correlated with explicit NA in acute depression but not during recovery. Conclusions Acute depression appears to be characterized by decreased implicit and explicit PA and increased implicit and explicit NA. After 7 weeks of treatment, depressed patients’ implicit and explicit PA increased, and explicit trait NA decreased. No decrease in implicit NA and explicit state NA occurred over the course of treatment. Finally, it seems that in the state of acute depression, the interplay between the automatic and reflective systems could be increased for negative affectivity.

AGE MODERATES THE ASSOCIATION BETWEEN IMPLICIT AND EXPLICIT NEGATIVE EMOTIONAL REACTIVITY

Background: According to the notion of maturational dualism, the link between mind and body weakens with age and this weakening has important consequences for emotional experiences. Specifically, it is hypothesized that age-related decline in interoceptive awareness and physiological reactivity reduce the ability to use bodily states to guide judgments about emotions. If this hypothesis is valid, then age may moderate the association between explicit measures (based on consciously accessible mental representations of affect) and implicit measures (based on unconscious affective processes such physiological activation) of affective reactivity. Purpose: To investigate whether age moderates the association between explicit and implicit measures of negative affective reactivity. Methods: A sample of 275 participants (age range=20-78) viewed 25 pictures validated to induce negative emotions. Participants filled in the PANAS assessing explicit affect and the IPANAT assessing implicit affect before and after viewing the pictures. Emotional reactivity was operationalized as residualized gain scores derived from regressions of baseline affect on affect following picture viewing. Results: Age moderated the association between implicit negative affective reactivity and explicit negative affective reactivity (B=60). Discussion: The results showed a reduced association between explicit and implicit negative affective reactivity with age. This finding is consistent with the notion of maturational dualism and may indicate that older adults use affective processes that are not represented consciously (e.g., physiological activation) less than young adults when judging their emotional state.

Advancing Issues in Motivation Intensity Research

What determines effort intensity in instrumental behavior? According to motivation intensity theory, effort should be proportional to experienced task difficulty as long as success is possible and justified and low when success is impossible or excessively difficult, given the available benefit. When task difficulty is unspecified or unknown, effort should be proportional to the importance of success. This chapter reports an extensive program of research that has operationalized effort intensity as cardiovascular reactivity during task performance and used multiple manipulations of variables influencing subjective task difficulty (e.g., performance standards, instrumentality, ability, fatigue, mood, depressive symptoms, implicit affect, implicit and biological aging) and the amount of justified effort (e.g., material incentive, instrumentality, needs, personal and social evaluation, mortality salience). In the second edition of this handbook, this chapter focuses on recent empirical evidence for the principles of motivation intensity theory and discusses challenges for other theoretical accounts.

Biosignals to Detect the Imbalance of Explicit and Implicit Affect in Dementia: A Pilot Study

Background: We assessed implicit and explicit emotion in older patients with dementia using biosignals. Methods: Fifty patients with dementia and 34 healthy individuals watched 3 videos that aimed to elicit various emotional responses. Electroencephalogram and heart rate variability were recorded. Results: Patients with dementia experienced less fun and more fear than controls. The high frequency (HF) from the baseline in response to funny stimulation as well as HF from neutral to fear stimulation in the dementia group increased further than in the control group. The slow wave (SW)–fast wave (FW) ratio from neutral to funny stimulation in the control group increased further than in the dementia group. The SW-FW from neutral to fear stimulation was further decreased in the dementia group than in the control group. Conclusions: Although patients with dementia were more sensitive to implicit affect, they showed more enhanced imbalance between positive and negative affect in explicit affect assessment.
