Affective Priming Task

Attenuated affective processing is hypothesized to play a role in the development and maintenance of obesity. Using an affective priming task measuring automatic affective processing of verbal stimuli, a group of 30 obese participants in a weight-loss program at the Psychosomatic University Clinic Bonn ( M age = 48.3, SD = 10.7) was compared with a group of 25 participants of normal weight ( M age = 43.6, SD= 12.5). A smaller affective priming effect was observed for participants with obesity, indicating less pronounced reactions to valenced adjectives. The generally reduced affective processing in obese participants was discussed as a possible factor in the etiology of obesity. Individuals who generally show less pronounced affective reactions to a given stimulus may also react with less negative affect when confronted with weight gain or less positive affect when weight is lost. Consequently, they could be expected to be less motivated to stop overeating or to engage in dieting and will have a higher risk of becoming or staying obese.

Affective Priming Task

AbstractBackgroundThere is evidence showing that men and women differ with regard to the processing of emotional information. However, the mechanisms behind these differences are not fully understood.MethodThe sample comprised of 275 (167 female) right-handed, healthy participants, recruited from the community. We employed a customized affective priming task, which consisted of three subtests, differing in the modality of the prime (face, written word, and sound). The targets were always written words of either positive or negative valence. The priming effect was measured as reaction time facilitation in conditions where both prime and target were emotional (of the same positive or negative valence) compared with conditions where the emotional targets were preceded by neutral primes.ResultsThe priming effect was observed across all three modalities, with an interaction of gender by valence: the priming effect in the emotionally negative condition in male participants was stronger compared with females. This was accounted for by the differential priming effect within the female group where priming was significantly smaller in the emotionally negative conditions compared with the positive conditions. The male participants revealed a comparable priming effect across both the emotionally negative and positive conditions.ConclusionReduced priming in negative conditions in women may reflect interference processes due to greater sensitivity to negative valence of stimuli. This in turn could underlie the gender-related differences in susceptibility to emotional disorders.

Abstract Background Obesity has emerged as a public health crisis in many populations including Egypt. Adipose tissue produces a number of adipokines, one of them is adiponectin which has attracted much attention because of its antidiabetic and antiatherogenic effects. Objective To determine the effect of a weight loss program on serum adiponectin level and insulin resistance among overweight and obese adult premenopausal females. Study design A pre-postintervention study was carried out among 95 premenopausal overweight and obese females (body mass index ≥ 25 kg/m2) aged 20 to 40 years at the integrated health clinic affiliated to the High Institute of Public Health, Alexandria, Egypt, from February 2016 to February 2017. All participants underwent a weight loss program based on a reduced calorie balanced diet and advised to increase their physical activity. Dietary instructions and follow-up were done weekly throughout 16 weeks. Blood samples were collected to investigate serum adiponectin level and insulin resistance at the beginning and the end of the intervention. Results After 16 weeks, a significant decrease in body weight by 9.7% was associated with a significant increase in serum adiponectin from 13.3 ± 4.9 μg/ml to 18.5 ± 5.6 μg/ml. Both fasting insulin and insulin resistance had decreased significantly by 13.6% and 13.7%, respectively. Conclusion A weight reduction program depending on a reduced calorie diet for 16 weeks was associated with a significant increase in total adiponectin level and reduction in insulin resistance. An emphasis on the importance of keeping normal weight through nutritional education and the promotion of healthy diets is recommended to reduce the risk of occurrence of insulin resistance, type 2 diabetes, and cardiovascular diseases.

Affective Information

Although studies have investigated the influence of the emotionality of primes on the cross-modal affective priming effect, it is unclear whether this effect is due to the contribution of the arousal or the valence of primes. We explored how the valence and arousal of primes influenced the cross-modal affective priming effect. In Experiment 1 we manipulated the valence of primes (positive and negative) that were matched by arousal. In Experiments 2 and 3 we manipulated the arousal of primes under the conditions of positive and negative valence, respectively. Affective words were used as auditory primes and affective faces were used as visual targets in a priming task. The results suggest that the valence of primes modulated the cross-modal affective priming effect but that the arousal of primes did not influence the priming effect. Only when the priming stimuli were positive did the cross-modal affective priming effect occur, but negative primes did not produce a priming effect. In addition, for positive but not negative primes, the arousal of primes facilitated the processing of subsequent targets. Our findings have great significance for understanding the interaction of different modal affective information.

Affective Priming Task

Krause et al. (2012) demonstrated that evaluative responses elicited by self-related primes in an affective priming task have incremental validity over explicit self-esteem in predicting self-serving biases in performance estimations and expectations in an anagram task. We conducted a conceptual replication of their experiment in which we added a behavioral and an affective outcome and presented names instead of faces as self-related primes. A heterogeneous sample (N = 96) was recruited for an online data collection. Name primes produced significantly positive and reliable priming effects, which correlated with explicit self-esteem. However, neither these priming effects nor explicit self-esteem predicted the cognitive, affective, or behavioral outcomes. Despite the lack of predictive validity of the implicit measure for affective and behavioral outcomes, the positive and reliable priming effects produced by name primes warrant the further investigation of the validity of the affective priming paradigm as a measure of implicit self-esteem.

It has been widely accepted that moral violations that involve impurity (such as spitting in public) induce the emotion of disgust, but there has been a debate about whether moral violations that do not involve impurity (such as swearing in public) also induce the same emotion. The answer to this question may have implication for understanding where morality comes from and how people make moral judgments. This study aimed to compared the neural mechanisms underlying two kinds of moral violation by using an affective priming task to test the effect of sentences depicting moral violation behaviors with and without physical impurity on subsequent detection of disgusted faces in a visual search task. After reading each sentence, participants completed the face search task. Behavioral and electrophysiological (event-related potential, or ERP) indices of affective priming (P2, N400, LPP) and attention allocation (N2pc) were analyzed. Results of behavioral data and ERP data showed that moral violations both with and without impurity promoted the detection of disgusted faces (RT, N2pc); moral violations without impurity impeded the detection of neutral faces (N400). No priming effect was found on P2 and LPP. The results suggest both types of moral violation influenced the processing of disgusted faces and neutral faces, but the neural activity with temporal characteristics was different.

Abstract Background Patients with cancer frequently experience malnutrition, which is associated with higher rates of morbidity and mortality. Therefore, the implementation of strategies for its early detection and for intervention should improve the evolution of these patients. Our study aim is to design and implement a protocol for outpatients starting chemotherapy, by means of which any malnutrition can be identified and treated at an early stage. Methods Before starting chemotherapy for patients with cancer, a complete assessment was made of their nutritional status, using the Nutriscore screening tool. When nutritional risk was detected, an interventional protocol was applied. Results Of 234 patients included in the study group, 84 (36%) required an individualised nutritional approach: 27 (32.1%) presented high nutritional risk, 12 had a Nutriscore result ≥ 5 and 45 experienced weight loss during chemotherapy. Among this population, the mean weight loss (with respect to normal weight) on inclusion in the study was − 3.6% ±8.2. By the end of the chemotherapy, the mean weight gain was 0% ±7.3 (p < 0.001) and 71.0% of the patients had experienced weight gain or maintenance, with respect to the initial weight. Conclusion More than a third of cancer patients who start chemotherapy are candidates for early nutritional intervention. This finding highlights the importance of early identification of patients at risk in order to improve the efficacy of nutritional interventions, regardless of the stage of the disease.

Abstract. People react with Rapid Facial Reactions (RFRs) when presented with human facial emotional expressions. Recent studies show that RFRs are not always congruent with emotional cues. The processes underlying RFRs are still being debated. In our study described herein, we manipulate the context of perception and its influence on RFRs. We use a subliminal affective priming task with emotional labels. Facial electromyography (EMG) (frontalis, corrugator, zygomaticus, and depressor) was recorded while participants observed static facial expressions (joy, fear, anger, sadness, and neutral expression) preceded/not preceded by a subliminal word (JOY, FEAR, ANGER, SADNESS, or NEUTRAL). For the negative facial expressions, when the priming word was congruent with the facial expression, participants displayed congruent RFRs (mimicry). When the priming word was incongruent, we observed a suppression of mimicry. Happiness was not affected by the priming word. RFRs thus appear to be modulated by the context and type of emotion that is presented via facial expressions.

Does the NIX18-campaign influence implicit and explicit cognitions in adults? Research has shown that often, the effectiveness of anti-alcohol mass media campaigns is not experimentally tested, meaning that it is unclear whether such campaigns are successful in altering alcohol-related cognitions. Therefore, in the present study, we investigated whether the Dutch NIX18-campaign is successful in influencing implicit associations (measured with an affective priming task) and explicit cognitions (i.e., alcohol outcome expectancies) concerning alcohol. Additionally, a possible relationship with negative evaluations of the campaign and psychological reactance was investigated. Participants implicit and explicit cognitions were measured before they were presented with either three NIX18-campaign movies or no movies (control condition). Subsequently, their implicit and explicit cognitions were measured again. Results show that whether participants watched the movies or not had no influence on implicit associations but increased alcohol outcome expectancies. No effect on evaluation and reactance was found. Possible theoretical and practical explanations are discussed.

Previous work from this laboratory has shown that chronic administration of dexfenfluramine (DF) caused substantial weight loss in rats that were overweight 3-4 mo after ovariectomy (OVX), but not in OVX rats that were of normal weight, as a result of estrogen replacement. The present study was conducted to determine whether the enhanced weight loss in the former group is because of either overweight per se or an inhibitory effect of estrogen on DF. Starting either 0, 6, or 14 wk after OVX, when weight gain was zero, moderate, or near maximal, respectively, rats received a 12-day regimen of either estradiol or the oil vehicle and either DF (3 mg.kg-1.day-1 by osmotic minipump) or no drug. DF had no effect on either food intake or weight gain of groups treated during 0-2 wk after OVX but had significant anorectic and weight loss actions in groups treated 6-8 and 14-16 wk after OVX. Estrogen had a similar effect at all three times and in the 14-wk group produced an effect that was additive with that of DF. Measures of plasma glucose and triglycerides and adipose tissue lipoprotein lipase activity did not correlate with the effectiveness of the drug to promote weight loss.
