Our research lab has found that individuals tend to adopt more extreme attitudes toward an outgroup (i.e., become self-radicalized) when they extrapolate from known to unknown traits about the outgroup. Recent lab findings have also suggested that trait imageability, or the ability to form a mental image of a trait, can influence the effects of extrapolation on self-radicalization, such that people were more likely to become self-radicalized when they extrapolated to traits that were relatively difficult, compared to relatively easy, to form a mental image of. The current experiment examined whether the effects of trait imageability on extrapolation also influence metacognitive outcomes. We found that participants who extrapolated to traits that were difficult to form a mental image of subsequently reported that they knew more about the outgroup, had greater confidence that they knew how the outgroup members would behave, and were more likely to believe the initial information about the outgroup was accurate, compared to participants who extrapolated to traits that were easy to form a mental image of and compared to control participants. The current findings established an important link between and the effects of trait imageability on extrapolation and subsequent metacognitive measures.

The growing population of Spanish speakers in the U.S. has created challenges related to translating and adapting interventions to serve this diverse population. This qualitative study examined how Trust-Based Relational Intervention® (TBRI®) practitioners currently handle challenges due to language and cultural issues among their primarily Spanish-speaking clients. Eight TBRI® practitioners in 4 different Latin American countries were recruited to complete an online background survey and a 30 to 45-minute virtual interview. Preliminary results indicate that TBRI® practitioners face challenges in regards to their clients’ education level, literacy rates, access to curriculum-related materials, and cultural views on the TBRI® correction principle. Practitioners handle these challenges by simplifying the language used in the materials, explaining content with culturally-relevant examples, creating items that can be used in lieu of ones used in the materials of curriculum, and having patience with clients as they learn a new way of parenting. The goal of this project is not only to bring awareness of translation language barriers and cultural issues with TBRI® materials but to help the Karyn Purvis Institute of Child Development adapt materials, so there is a more appropriate and easily received response to the material among primarily Spanish-speaking children and families.

A foreign language is a non-native language acquired outside of a natural linguistic community. The benefits of learning a foreign language include that it heightens employability, positively affects cognitive functioning, and increases cross-cultural awareness. The goal of this study was to compare the effects of a pair-test (PT) procedure and a high-density response construction (HDRC) procedure on foreign-language vocabulary acquisition. We used a within-subjects pretest-posttest design combined with a single-subject multielement design. Nine participants received instructions with 10 Arabic words; 5 words were taught via HDRC instruction, and 5 via pair-test. We hypothesized that participants would learn faster in the HDRC condition and perform better on transfer and retention tests. However, preliminary results suggest that there was no difference between conditions.

Previous research evaluated the extent to which equivalence-based instruction (EBI) is more efficient or produces stimulus classes with different properties than complete instruction (CI) in which all relations between stimuli in a class are taught directly. The purpose of the present study was to evaluate the flexibility of the formed stimulus classes in EBI and CI procedures with a contingency reorganization. Forty-eight undergraduate students received training to establish 3 stimulus classes with 4 members in each class. The students were randomly assigned to two groups: EBI – in which they received training for some of the relations – and CI – that targeted all possible relations between the members of each class. After undergoing training and equivalence test (Phase 1), participants received contingency reorganization training (Phase 2). In the reorganization phase, the relations A1B2, A2B3, A3B1 were stablished as correct. Class flexibility was evaluated in an immediate contingency-reversal post-test. The EBI group required fewer training trials to complete ABCD training, and performed similarly to the CI group in the equivalence test. Additionally, EBI group required less training trials in the reorganization training, and performed better in the reorganization test when compared to CI group.

I examined the effects of disrupting verbal mediation in a task that models the effects of verbally presented information on conceptual behavior. The experiment was done asynchronously by sending participants a SuperLab 6.0 software experiment, requesting a screen recording using Zoom, and acquiring demographic, consent, and exit interview information using Qualtrics. Sixty-four participants were randomly assigned to four conditions. The tact-intraverbal (TI) groups first learned to match visual stimuli with verbal labels, and then to associate pairs of verbal labels. The intraverbal-tact (IT) groups received the opposite sequence. After training, all groups were tested for new relationships between the visual stimuli. One TI group and one IT group were given an additional verbal task during the test, which was predicted to disrupt the performance more in the IT than the TI condition, due to IT participants being more reliant on solving the task verbally. No significant differences in accuracy or reaction time were noted between groups. However, only 47% of those in the IT-V group and 13% of those in the TI-V group actually performed the additional verbal task. The experiment should be repeated through real-time video calls or in person, so that participant instruction-following can be monitored and intervened on.
