Self-recognition is a key indicator of higher cognitive processing and is atypical in children with autism spectrum disorder. A normal hallmark of typical social development requires knowledge of self and others. Self-recognition has been tested in a variety of different species and has been seen in a small number of mammals, birds, and fish. It is classically demonstrated by visual recognition using the mirror mark test. Parishar et al. (2021) previously examined self-recognition in zebra finches (Taeniopygia guttata), and despite some potentially promising findings, none of the birds in their experiments passed the mirror mark test. This study sought to extend previous research by exploring whether zebra finches demonstrate self-recognition using a more thorough and exhaustive procedure exposing zebra finches to a mirror following the application of visible mark. Six male zebra finches were habituated to an experimental cage and were exposed to four different conditions (mirror, male bird, female bird, control). Then, two analyses were performed: Experiment 1 examined whether zebra finches change the spectrotemporal features of song in each of the four conditions, and Experiment 2 assessed whether birds attempted to inspect or remove a mark only visible when birds viewed their reflection in a mirror in each condition. Observations suggest that some birds may show attention towards the mark test because as seen by mark-directed behavior. Song characteristics will be explored to determine if zebra finches modify their song structure when facing a mirror compared to singing to a male bird, a female bird, or an empty cage (control). This would provide evidence supporting self-recognition if the singing behavior directed toward the mirror is distinct from that toward a conspecific. This study explores whether self-recognition is observed in zebra finches, providing insight into evolutionary and cognitive mechanisms of self-recognition that can be used for future studies in the neurobiology of social and cognitive behaviors.

Existential Isolation and Its Impact on Empathy and Perspective Taking

Existential Isolation (EI) is the experience of feeling as though you are alone in your experience of the world; and that those around you do not share or understand your experiences. Past research demonstrates that EI is associated with negative influences on personal well-being including: loneliness, depression, anxiety, and lower levels of self-esteem. The impact of EI on our interactions or perceptions of others is less known and understood. Individuals that feel existentially isolated perceive a disconnect between how they experience the world and how others experience the world. Due to this disconnect, people with higher levels of EI may have difficulty taking the perspective of others or “walking in someone else’s shoes”. Perspective taking is a vital cognitive factor for feeling empathetic towards others. To explore if EI is associated with less empathy for others due to a difficulty in perspective taking, 186 undergraduate students were presented with three short stories depicting someone experiencing stress (e.g., recently experienced the death of a parent), and asked to try taking the perspective of the people in the stories. Results indicated that people who reported greater feelings of EI also reported greater difficulty with perspective taking and, subsequently, reported feeling less empathy for the people in the stories. These findings suggest that EI may inhibit people’s feelings of empathy due to increasing their difficulty with perspective taking. The implications of these findings for the role of EI in helping and supporting behaviors are discussed.

In conjunction with the legalization of medical marijuana, there has been an increase in recreational marijuana use among youth. In 2016, marijuana use for youth in the legal system (YLS) hit a high of 64%, which far exceeded the 11% rate for youth outside the legal system. Youth that frequently or occasionally use marijuana are linked to adverse health problems, including both physical and emotional, and have poor school outcomes. Prior research has found that youth who use marijuana are more susceptible to emotional dysregulation and higher levels of anxiety. Higher anxiety levels have been linked to greater marijuana use, more significant anxiety symptoms, and increases in anxiety over time. This is concerning as research shows that youth with higher levels of anxiety sensitivity, or fear of anxiety, used marijuana to detach or manage emotional distress. Due to the risks associated with cannabis use, this study examined marijuana use among a sample of YLS, specifically looking at its connection to both emotion dysregulation and anxiety. Data were utilized over three timepoints (i.e., baseline, 3-month follow-up, and 6-month follow-up) from a 5-year longitudinal study. Consistent with prior research, it is expected that there would be a positive relationship between anxiety and marijuana use, as well as emotion dysregulation and marijuana use. Utilizing Pearson’s correlations, results indicated a significant negative relationship between marijuana use and the emotion dysregulation subscale of nonacceptance at baseline. However, there were no significant relationship between marijuana use and anxiety. At month 3 follow-up, there were significant positive relationships between marijuana use and anxiety, as well as marijuana use and emotion dysregulation for total scores and the nonacceptance subscale. At the month 6 follow-up, results indicated a positive relationship between marijuana use and anxiety. However, there was no longer a significant relationship between marijuana use and emotion dysregulation. These preliminary results suggest there is a complicated relationship between emotion dysregulation and anxiety when it comes to marijuana use. Future research should continue examining these relationships to better inform intervention work.

Panic disorder is a debilitating mental health disorder characterized by recurrent panic attacks, fear of future panic attacks and maladaptive behavioral changes. While only 4.7% of Americans will battle panic disorder in their lifetime, 27.3% of Americans will experience at least one panic attack. Cognitive models of panic attacks have historically emphasized the role of anxiety sensitivity in predicting symptoms, but other transdiagnostic variables, such as thought suppression, have yet to be explored. The purpose of this study was to test the ability of thought suppression to predict panic symptom severity above and beyond other predictors. To do this, we recruited participants (N = 161) on Cloud Research using Amazon's Mechanical Turk (MTurk) Toolkit. Participants completed an online survey consisting of self-report measures of panic symptom severity, thought suppression, anxiety sensitivity, and trait anxiety. Results of simultaneous and hierarchical multiple regressions revealed that thought suppression was a significant positive predictor of panic symptom severity and accounted for additional variance in the model above and beyond anxiety sensitivity and trait anxiety. This unique finding suggests that perhaps attempts to suppress anxious or catastrophic thoughts strengthens them and feeds the panic cognitive loop. It also supports the exploration of acceptance-based interventions to address thought suppression differently than traditional cognitive-behavioral therapy.

Prior research has found that visual cues presented before (pre) or after (retro) an object improve object properties recognition, like identity (what it is) and spatial location (where it is), in humans (Griffin & Nobre, 2003) and monkeys (Brady & Hampton, 2018). However, this has not yet been tested in other species or using other cue modalities (e.g., auditory). The current experiment will analyze the effect of visual and auditory cues on object recognition in 6 pigeons, explicitly examining how these cues influence identity and spatial location processing in a visual working memory task.

Pigeons will perform a change detection task,in a Plexiglas chamber with a monitor, touch screen, and speakers. In each trial, the subject will peck a white crosshair on the center of the screen to start. After 1500 ms, a sample pair of colored circles will appear on the left and right sides of the screen for 5000 ms. After a 1500 ms delay, a test stimulus will be displayed on the screen’s left or right side. Pigeons must compare the test stimulus to the sample previously presented on the same side of the screen. During some trials, pigeons will receive pre- or retro-cue signaling which sample stimulus will be tested (e.g., the one displayed on the left). For half of the pigeons, the cues will be different frequency sounds (auditory group), and for the rest, colored backgrounds (visual group). It is predicted that the auditory group will have higher accuracy than the visual group, suggesting auditory cues may enhance recognition of visual objects more than visual cues.
