Expectations Do Not Always Influence Food Liking
The purpose of the present experiment was to examine how expectations influence cracker ratings on a scale of likeability. A large body of research shows that expectations affect food experiences (Wansink, 2004; Eertmans, Baeyens & Van den Bergh, 2001; Kahkonen & Tuorila, 1998). Participants were not aware that the primary interest of the study was how expectations influence cracker ratings. Participants were assigned to either a positive expectation group or a neutral expectation group. Participants in the positive expectation group received a positive verbal cue indicating that the crackers had recently been rated high in a national taste test. The neutral expectation group did not receive the information concerning the national taste test. Participants were administered critical thinking tasks while consuming crackers. It was hypothesized that those in the positive expectation group would rate the crackers higher than those in the neutral expectation group. The results of the study did not support the hypothesis. There was no difference in how the groups rated the crackers
The intelligence quotient in justice
This project was designed to research information about intellectually disabled individuals in the criminal justice system. The beginning stages of this project focused on defining intellectual and developmental disabilities as well as the testing that is utilized to determine intellectual disabilities. Additional information that was searched for included characterizing crimes that are committed by individuals with intellectual or developmental disabilities and the questioning techniques that would be utilized during the first stages of the judicial process. The final aspect included rehabilitation programs that are being utilized for offenders with intellectual disabilities. The final stages of this project included risk factors, programs that have worked for adults with intellectual disabilities and reentry into the community. The recommendations incorporate issues from when an individual would come into contact with an officer, interrogation, the legal team, intake, habilitation and reentry
Are you on my wavelength? Interpersonal coordination in dyadic conversations
Conversation between two people involves subtle non-verbal coordination in addition to speech. However, the precise parameters and timing of this coordination remain unclear, which limits our ability to theorise about the neural and cognitive mechanisms of social coordination. In particular, it is unclear if conversation is dominated by synchronisation (with no time lag), rapid and reactive mimicry (with lags under 1 second) or traditionally observed mimicry (with several seconds lag), each of which demands a different neural mechanism. Here we describe data from high-resolution motion capture of the head movements of pairs of participants (n=31 dyads) engaged in structured conversations. In a pre-registered analysis pathway, we calculated the wavelet coherence of head motion within dyads as a measure of their non-verbal coordination and report two novel results. First, low frequency coherence (0.2-1.1Hz) is consistent with traditional observations of mimicry, and modelling shows this behaviour is generated by a mechanism with a constant 600msec lag between leader and follower. This is in line with rapid reactive (rather than predictive or memory-driven) models of mimicry behaviour, and could be implemented in mirror neuron systems. Second, we find an unexpected pattern of lower-than-chance coherence between participants, or hypo-coherence, at high frequencies (2.6-6.5Hz). Exploratory analyses show that this systematic decoupling is driven by fast nodding from the listening member of the dyad, and may be a newly identified social signal. These results provide a step towards the quantification of real-world human behaviour in high resolution and provide new insights into the mechanisms of social coordination
Wide-field dynamic astronomy in the near-infrared with Palomar Gattini-IR and DREAMS
There have been a dramatic increase in the number of optical and radio transient surveys due to astronomical transients such as gravitational waves and gamma ray bursts, however, there have been a limited number of wide-field infrared surveys due to narrow field-of-view and high cost of infrared cameras, we present two new wide-field near-infrared fully automated surveyors; Palomar Gattini-IR and the Dynamic REd All-sky Monitoring Survey (DREAMS). Palomar Gattini-IR, a 25 square degree J-band imager that begun science operations at Palomar Observatory, USA in October 2018; we report on survey strategy as well as telescope and observatory operations and will also providing initial science results. DREAMS is a 3.75 square degree wide-field imager that is planned for Siding Spring Observatory, Australia; we report on the current optical and mechanical design and plans to achieve on-sky results in 2020. DREAMS is on-track to be one of the first astronomical telescopes to use an Indium Galium Arsenide (InGaAs) detector and we report initial on-sky testing results for the selected detector package. DREAMS is also well placed to take advantage and provide near-infrared follow-up of the LSST
PTF10fqs: A Luminous Red Nova in the Spiral Galaxy Messier 99
The Palomar Transient Factory (PTF) is systematically charting the optical
transient and variable sky. A primary science driver of PTF is building a
complete inventory of transients in the local Universe (distance less than 200
Mpc). Here, we report the discovery of PTF10fqs, a transient in the luminosity
"gap" between novae and supernovae. Located on a spiral arm of Messier 99, PTF
10fqs has a peak luminosity of Mr = -12.3, red color (g-r = 1.0) and is slowly
evolving (decayed by 1 mag in 68 days). It has a spectrum dominated by
intermediate-width H (930 km/s) and narrow calcium emission lines. The
explosion signature (the light curve and spectra) is overall similar to thatof
M85OT2006-1, SN2008S, and NGC300OT. The origin of these events is shrouded in
mystery and controversy (and in some cases, in dust). PTF10fqs shows some
evidence of a broad feature (around 8600A) that may suggest very large
velocities (10,000 km/s) in this explosion. Ongoing surveys can be expected to
find a few such events per year. Sensitive spectroscopy, infrared monitoring
and statistics (e.g. disk versus bulge) will eventually make it possible for
astronomers to unravel the nature of these mysterious explosions.Comment: 12 pages, 12 figures, Replaced with published versio
Constraining the X-ray - Infrared spectral index of second-timescale flares from SGR1935+2154 with Palomar Gattini-IR
The Galactic magnetar SGR1935+2154 has been reported to produce the first
known example of a bright millisecond duration radio burst (FRB 200428) similar
to the cosmological population of fast radio bursts (FRBs), bolstering the
association of FRBs to active magnetars. The detection of a coincident bright
X-ray burst has revealed the first observed multi-wavelength counterpart of a
FRB. However, the search for similar emission at optical wavelengths has been
hampered by the high inferred extinction on the line of sight. Here, we present
results from the first search for second-timescale emission from the source at
near-infrared wavelengths using the Palomar Gattini-IR observing system in
J-band, made possible by a recently implemented detector read-out mode that
allowed for short exposure times of 0.84 s with 99.9% observing efficiency.
With a total observing time of 12 hours (47728 images) on source, we place
median limits on the second-timescale emission of mJy (13.1
AB mag). We present non-detection limits from epochs of four simultaneous X-ray
bursts detected by the Insight-{\it HXMT} and {\it NuSTAR} telescopes during
our observing campaign. The limits translate to an extinction corrected fluence
limit of Jy ms for an estimated extinction of mag. These
limits provide the most stringent constraints to date on the fluence of flares
at frequencies of Hz, and constrain the ratio of the
near-infrared (NIR) fluence to that of coincident X-ray bursts to . Our observations were sensitive enough to easily detect
a near-infrared counterpart of FRB 200428 if the NIR emission falls on the same
power law as that observed across its radio to X-ray spectrum. The
non-detection of NIR emission around the coincident X-ray bursts constrains the
fluence index of the brightest burst to be steeper than .Comment: 10 pages, 4 figures, submitted to ApJL. Comments welcom

Palomar Gattini-IR: Survey overview, data processing system, on-sky performance and first results
Palomar Gattini-IR is a new wide-field, near-infrared (NIR) robotic time domain survey operating at Palomar Observatory. Using a 30 cm telescope mounted with a H2RG detector, Gattini-IR achieves a field of view (FOV) of 25 sq. deg. with a pixel scale of 8.”7 in J-band. Here, we describe the system design, survey operations, data processing system and on-sky performance of Palomar Gattini-IR. As a part of the nominal survey, Gattini-IR scans ≈7500 square degrees of the sky every night to a median 5σ depth of 15.7 AB mag outside the Galactic plane. The survey covers ≈15,000 square degrees of the sky visible from Palomar with a median cadence of 2 days. A real-time data processing system produces stacked science images from dithered raw images taken on sky, together with point-spread function (PSF)-fit source catalogs and transient candidates identified from subtractions within a median delay of ≈4 hr from the time of observation. The calibrated data products achieve an astrometric accuracy (rms) of ≈0.”7 with respect to Gaia DR2 for sources with signal-to-noise ratio > 10, and better than ≈0.”35 for sources brighter than ≈12 Vega mag. The photometric accuracy (rms) achieved in the PSF-fit source catalogs is better than ≈3% for sources brighter than ≈12 Vega mag and fainter than the saturation magnitude of ≈8.5 Vega mag, as calibrated against the Two Micron All Sky Survey catalog. The detection efficiency of transient candidates injected into the images is better than 90% for sources brighter than the 5σ limiting magnitude. The photometric recovery precision of injected sources is 3% for sources brighter than 13 mag, and the astrometric recovery rms is ≈0.”9. Reference images generated by stacking several field visits achieve depths of ≳16.5 AB mag over 60% of the sky, while it is limited by confusion in the Galactic plane. With a FOV ≈40× larger than any other existing NIR imaging instrument, Gattini-IR is probing the reddest and dustiest transients in the local universe such as dust obscured supernovae in nearby galaxies, novae behind large columns of extinction within the galaxy, reddened microlensing events in the Galactic plane and variability from cool and dust obscured stars. We present results from transients and variables identified since the start of the commissioning period
