RESUMEN
Cognitive enrichment is becoming more prevalent in professional marine mammal facilities. Research with dolphins has suggested that such enrichment provides more welfare benefits than enrichment that does not incorporate cognitive challenge. However, there is little research supporting the use of cognitive enrichment as a means to improve the welfare of sea lions. Recently, a novel form of technological cognitive enrichment, the Enclosure Video Enrichment (EVE) system, was introduced to a population of California sea lions at the US Navy's Marine Mammal Program as a means to enhance welfare. Two of the initial focal animals introduced to EVE were selected based on their health history and the possible benefits of cognitive enrichment in improving health measures. To evaluate this, information regarding the animals' consumption of their offered diet was compared to other animals in the population of similar age and the absence of a similar health history. Subsequently, the total diet consumption of the targeted animals was evaluated in the two years prior to the introduction to EVE and compared to the total diet consumption during the initial 2 years of regular EVE sessions. There was a significant decrease in the number of days in which the sea lions did not consume their entire offered diet in the two years after implementing regular EVE sessions, an increase in participation and performance of voluntary husbandry behaviors, and a reduction in the number of days animals were clinically ill. This study provides evidence of cognitive enrichment as a management tool to improve animal health and welfare as well as performance in training sessions.
RESUMEN
OBJECTIVE: Latinx youth exhibit disproportionately higher internalizing symptoms than their peers from other racial/ethnic groups. This study compares depression and anxiety symptoms between referred students of Latinx and non-Latinx backgrounds before and during the COVID-19 pandemic and examines key determinants within the Latinx sample. METHOD: Data are analyzed from four academic years - two before and two during the pandemic - from 1220 5th through 8th grade students (Mage = 12.1; 59.6% female; 59.9% Latinx or mixed-Latinx) referred for services across 59 Chicago Public School District (CPS) elementary schools. Using the Children's Depression Inventory (CDI) and the Revised Child Anxiety and Depression Scale (RCADS), mean scores and risk levels for depression, social anxiety, and generalized anxiety are examined. RESULTS: Higher internalizing risk and comorbidity rates were found in the second year of the pandemic, compared to pre-pandemic levels. Latinx students reported higher depression, social anxiety, and generalized anxiety symptoms than non-Latinx students. During the pandemic, more Latinx students were classified as having comorbid depression and anxiety, and scored in the clinical range for depression, generalized anxiety, and social anxiety than non-Latinx students. Within the Latinx sample, girls and gender non-conforming students reported the highest maladjustment. CONCLUSIONS: Results highlight the pressing need to examine the long-term impact of COVID-19 on the mental health of Latinx children and adolescents, and to address their internalizing problems.

The purpose of the current study was to evaluate the effects of equivalence-based instruction (EBI) on the emergence of basic music reading and piano playing skills. Six female college students learned to identify three musical chord notations given their respective dictated names. Participants also learned to play chords on the piano following the dictated name of the chord, and to play the chords to a song on a keyboard. Results are consistent with past research, in that stimuli became substitutable for each other and acquired a common behavioral function. Data suggest that EBI was an effective and efficient procedure to teach adults to read musical notation, as well as play chords and a song on a piano keyboard.
