The Impact of the Safe Conversations Workshop With Diverse,Low-Income Couples

The purpose of this study was to investigate the effectiveness of the Safe Conversations workshop with low income, racial and ethnic minority couples. A sample of 156 individuals (N = 156) participated in a relationship workshop developed by Harville Hendrix and Helen LaKelly Hunt which utilized the theory and practice of Imago Relationship Therapy (IRT). Participants were administered the Dyadic Adjustment Scale before and after the workshop. Findings indicated statistical significance in their overall DAS score and a large effect size in one of four relationship subscales: Consensus. Both males and females were found to derive benefits from the workshop at equal rates.     

Doing as they would do: How the perceived ethical preferences of third-party beneficiaries impact ethical decision-making

Although unethical behavior often benefits third-parties not directly complicit in the misconduct, not all beneficiaries welcome these ill-gotten benefits. We investigate whether actors consider the ethical preferences of potential beneficiaries or rely solely on their own ethical predispositions when making decisions that affect others. Three studies demonstrate that the perceived ethical preferences of these beneficiaries can substantially influence the likelihood that actors behave unethically on their behalves. These studies show that actors consider the ethical preferences of beneficiaries only when their own ethical disposition is outcome-based.     

Dishonesty in the Name of Equity

ABSTRACT— Under what conditions do people act dishonestly to help or hurt others? We addressed this question by examining the influence of a previously overlooked factor—the beneficiary or victim of dishonest acts. In two experiments, we randomly paired participants and manipulated their wealth levels through an initial lottery. We then observed how inequity between partners influenced the likelihood of one dishonestly helping or hurting the other, while varying the financial incentives for dishonest behavior. The results show that financial self-interest cannot fully explain people's tendency to dishonestly help or hurt others. Rather, such dishonesty is influenced by emotional reactions to wealth-based inequity, even when the dishonesty bears a personal financial cost. Envy evoked by negative inequity led to hurting behavior, whereas guilt induced by positive inequity motivated helping behavior. Finally, inequity between the partner and third parties triggered dishonest helping through empathy with the partner.     

Comparison of deck- and trial-based approaches to advantageous decision making on the Iowa Gambling Task

We compared the original deck-based model of advantageous decision making assessed with the Iowa Gambling Task (IGT) with a trial-based approach across behavioral and physiological outcomes in 33 younger adults (15 men, 18 women; 22.2 ± 3.7 years of age). One administration of the IGT with simultaneous measurement of skin conductance responses (SCRs) was performed and the two methods applied: (a) the original approach of subtracting disadvantageous picks of Decks A and B from advantageous picks of Decks C and D and (b) a trial-based approach focused on the financial outcome for each deck leading up to the trial in question. When directly compared, the deck-based approach resulted in a more advantageous behavioral profile than did the trial-based approach. Analysis of SCR data revealed no significant differences between methods for physiological measurements of SCR fluctuations or anticipatory responses to disadvantageous picks. Post hoc investigation of the trial-based method revealed Deck B contributed to both advantageous and disadvantageous decision making for the majority of participants. When divided by blocks of 20, the number of advantageous to disadvantageous choices reversed as the task progressed despite the total number of picks from Deck B remaining high. SCR fluctuations for Deck B, although not significantly different from the other decks, did show a sharp decline after the first block of 20 and remained below levels for Decks C and D toward the end of the task, suggesting that participants may have gained knowledge of the frequency of loss for this deck.     

An investigation of the interaural time difference threshold for speech

The interaural time difference threshold for speech has been reported to be approximately 35 μsec (Cherry & Sayers, 1956), a value substantially larger than the 6 ~sec reported for broadband noise signals by other experimenters (e.g., Tobias & Zerlin, 1959). In the two studies just mentioned, however, different subjects and psychoacoustical methods were employed; thus, it is unclear whether larger interaural time differences are needed to lateralize speech signals. The purpose of this experiment, therefore, was to compare lateralization performance for speech and nonspeech stimuli. Interaural time difference thresholds were obtained for speech, speech spectrum noise, speech multiplied noise, and 200-, 500-, and 1,000-Hz sinusoids for the same subjects using a 2 IFC experimental paradigm. Under these conditions, speech and speech-multiplied noise yielded essentially the same interaural time difference thresholds.     

The abundance effect: Unethical behavior in the presence of wealth

Three laboratory studies investigated the hypothesis that the presence of wealth may influence people’s propensity to engage in unethical behavior for financial gain. In the experiments, participants were given the opportunity to cheat by overstating their performance on an anagram task. In each study, one group was stimulated by the visible proximity of monetary wealth. We found that the presence of abundant wealth led to more frequent cheating than an environment of scarcity. Our experiments also investigated the potential mechanisms behind this effect. The results showed that the presence of abundant wealth provoked feelings of envy toward wealthy others that, in turn, led to unethical behavior. Our findings offer insights into when and why people engage in unethical behavior.

The use of olfactory cues in solving a visual discrimination task

Albino rats, trained in a miniaturized WGTA, were found to learn an olfactory discrimination despite the fact that visual cues were relevant and obvious. The results provide a further warning against the use of macrosmatic animals in visual discrimination tasks in which olfactory cues may be relevant.
