Description
Color is an inseparable part of our world as it exists in everything we perceive (Hemphill, 1996). With this constant exposure to colors, it has been widely acknowledged that colors have a distinct effect on a person's feelings and emotions (Hemphill, 1996). In fact, researcher have found that color perception evolved as an adaptation to increase fitness for animals (Bryne & Hilbert, 2003). For humans, color is a part of many everyday associations from temperature to traffic lights to sporting events. Taking this a step further, researchers have studied the effects of color on psychological functioning and physiological responses, including anxiety. A substantial body of research developed a base of information to support the idea that color has a significant effect on humans' emotions, perceptions and behaviors. I set out to test the effects of color on test anxiety and the relationship between anxiety and test performance. It was hypothesized that paper colors red, blue, and green would have an effect on anxiety with red having the most robust effect. It was also hypothesized that there would be a correlation between test performance and anxiety. Fifty undergraduate students took a ten-question brainteaser test printed on one of the three paper colors. Results displayed a significant mead difference between the three test group colors and a significant correlation between test performance and anxiety. This study was then repeated using the colors white, blue, and red. Fifty-eight undergraduate students took the same ten-question brainteaser test. These results failed to suggest a significant mean difference between the three test groups and failed to suggest a correlation between performance and anxiety. These findings conflict with the first study, and therefore, are of interest. Possibilities for these findings are the frequency of occurrence of white and social desirability. Future directions include testing for trait anxiety prior to data collection and using physiological measures to test anxiety. Still, these results can be applied in classroom settings, office environments, and airports.

Description
Recent findings support that facial musculature accounts for a form of phonetic sound symbolism. Yu, McBeath, and Glenberg (2019) found that, in both English words and Mandarin pinyin, words with the middle phoneme /i:/ (as in “gleam”) were rated as more positive than their paired words containing the phoneme /ʌ/ (as in “glum”). The present study tested whether a second largely orthogonal dimension of vowel phoneme production (represented by the phonemes /æ/ vs /u/), is related to a second dimension perpendicular to emotional valence, arousal. Arousal was chosen because it is the second dimension of the Russell Circumplex Model of Affect. In phonetic similarity mappings, this second dimension is typically characterized by oral aperture size and larynx position, but it also appears to follow the continuum of consonance/dissonance. Our findings supported the hypothesis that one-syllable words with the center vowel phoneme /æ/ were reliably rated as more rousing, and less calming, than matched words with the center vowel phoneme /u/. These results extend the Yu, et al. findings regarding the potential contribution of facial musculature to sounds associated with the emotional dimension of arousal, and further confirm a model of sound symbolism related to emotional expression. These findings support that phonemes are not neutral basic units but rather illustrate an innate relationship between embodied emotional expression and speech production.

Description
We compared sociability towards humans of domesticated and tame members of several Canidae: Belyaev's fox (Vulpes vulpes), red fox (Vulpes vulpes), gray wolf (Canis lupus), dingo (Canis l. dingo), New Guinea singing dog (Canis l. dingo), and dog (Canis l. familiaris). We defined sociability as motivation or willingness to engage with humans. Our operationalized definition of sociability is the latency to approach (LTA) the human experimenter and the amount of time the canid spent within one meter of the human experimenter (PTC). We added an unfamiliar and familiar experimenter condition to deduce whether or not canids discriminated on who they were more social with: an owner or a stranger. To each experimenter condition we added a passive and active phase to discern whether or not canids were more social when called or not. Across all conditions and phases dogs were significantly more social than all other canid types. We concluded genetic differences due to domestication and environmental differences due to socialization accounted for sociability differences seen in dogs compared to the other canid types.

Description
This study investigates the effects of familiarity and the size of a novel object on perception of depth. Familiar size is a visual depth cue that provides information about the distance of an object. This project explores if the familiar size illusion is a result of an automatic perceptual process or an intellectual thought process. This data was collected in two phases, a familiarization phase and a testing phase. The experimental participants were familiarized for 30 seconds with a novel object, while the control group was not shown any objects prior to presentation of test objects. The novel test stimuli were constructed in 5 sizes and participants in the familiar group were familiarized with the medium size object. Participants were then asked to indicate the perceived distance of different sized objects by moving a rod with a pointer at the end to match the distance. The smaller comparison objects subtended visual angles that participants had not previously experienced, while larger comparison objects produced a larger visual angle than the participants had seen during the familiarization phase. The testing phase was identical for both familiar and unfamiliar control groups. Apparent distance was influenced by the size of the objects. Larger objects were judged to be closer than the smaller objects. Participants not familiarized showed smaller effects of stimulus size than the familiarized group. The effect of familiarity was not significant for the smaller stimuli but was very significant for the larger stimuli. The results were not consistent with the cognitive theory which argues that familiar size is a result of a conscious thought process. These outcomes are predicted under the model of familiar size being an automatic perceptual process.

The Wham-Womb Sound Symbolic Effect: English-Speaking Children and Adults Link Phonemes with Arousal
Description
Sound symbolism—the association between word sounds and meaning—has been shown to be an effective communication tool that promotes language comprehension and word learning. Much of the literature is constrained to investigating sound as it relates to physical characteristics (e.g. size or shape), and research has predominantly studied the phenomenon in adults. The current study examined the sound symbolic wham-womb effect, which postulates that words with the /æ/ phoneme are associated with increased arousal while words with the /u/ phoneme are associated with little to no arousal. The effect was tested in both adults and children aged 5-7 years old using a word-to-scene matching task. Participants were presented with two pseudowords (differing only by their vowel phoneme: /æ/ or /u/; e.g. smad and smood) and two scenes depicting an animal in either a more arousing or less arousing situation. Participants were then asked to match which of the scenes fit one of the pseudowords. Results showed that the trial-by-trial performance for adults and children were significantly greater than chance, indicating that the wham-womb effect is exhibited in both adults and children. There was also a significant difference in performance between adults and children, with adults showing a more robust effect. This study provides the first empirical evidence that both children and adults link phonemes to arousal and that this effect may change across development.

Description
In baseball, the difference between a win and loss can come down to a single call, such as when an umpire judges force outs at first base by typically comparing competing auditory and visual inputs of the ball-mitt sound and the foot-on-base sight. Yet, because the speed of sound in air only travels about 1100 feet per second, fans observing from several hundred feet away will receive auditory cues that are delayed a significant portion of a second, and thus conceivably could systematically differ in judgments compared to the nearby umpire. The current research examines two questions. 1. How reliably and with what biases do observers judge the order of visual versus auditory events? 2. Do observers making such order judgments from far away systematically compensate for delays due to the slow speed of sound? It is hypothesized that if any temporal bias occurs it is in the direction consistent with observers not accounting for the sound delay, such that increasing viewing distance will increase the bias to assume the sound occurred later. It was found that nearby observers are relatively accurate at judging if a sound occurred before or after a simple visual event (a flash), but exhibit a systematic bias to favor visual stimuli occurring first (by about 30 msec). In contrast, distant observers did not compensate for the delay of the speed of sound such that they systematically favored the visual cue occurring earlier as a function of viewing distance. When observers judged simple visual stimuli in motion relative to the same sound burst, the distance effect occurred as a function of the visual clarity of the ball arriving. In the baseball setting, using a large screen projection of baserunner, a diminished distance effect occurred due to the additional visual cues. In summary, observers generally do not account for the delay of sound due to distance.
