笑声也会感染倭黑猩猩
#科学

一项研究发现,倭黑猩猩在听到笑声后,更可能去接近一个平时不会触碰的东西。这项研究对 4 只经过训练的倭黑猩猩进行了监测,它们会根据盒子是否装有食物而与盒子互动或忽略盒子,这项研究表明,听到积极的声音可能会影响它们的觅食和搜索行为。在研究中,4 只倭猩猩被安排熟悉一个有食物奖励的黑盒子和一个空的白盒子,并被训练按一个按钮拒绝白盒子。此外,有 3 个“模棱两可”的盒子(浅灰、中灰和深灰)间歇呈现,在50% 的盒子中含有食物奖励。测试在播放倭猩猩笑声或环境风声的情况下进行,播放时间持续7分28秒。研究显示,倭猩猩在93%的情况下会接近黑盒子,仅在1%的情况下接近白盒子。而在提供灰色盒子时,倭黑猩猩接近深灰盒子的情况较浅灰的频繁。综合所有灰色盒子的试验结果,研究人员发现,倭灰猩猩在听到笑声录音后更容易检查灰色盒子,其接近灰盒子的概率较环境风声的情况高了3.4倍。研究人员认为,笑声可能引发了倭黑猩猩的情感共鸣,影响了它们的行为,使其更容易接近一个模棱两可的刺激物。

Pinterest (PINS) Stock Sinks As Market Gains

Pinterest (PINS) closed at $71.75 in the latest trading session, marking a -0.18% move from the prior day. This change lagged the S&P 500's daily gain of 0.1%. Meanwhile, the Dow gained 0.9%, and the Nasdaq, a tech-heavy index, lost 0.59%. Heading into today, shares of the digital pinboard and shopping tool company had lost 17.41% over the past month, lagging the Computer and Technology sector's loss of 5.38% and the S&P 500's gain of 0.71% in that time. Investors will be hoping for strength from PINS as it approaches its next earnings release. The company is expected to report EPS of $0.07, up 170% from the prior-year quarter. Our most recent consensus estimate is calling for quarterly revenue of $467.87 million, up 72.05% from the year-ago period.

The messaging service and social-media platform owes creditors roughly $700 million by the end of April, according to people briefed on the company’s plans and loan documents viewed by The Wall Street Journal. At the same time, Telegram Group Inc. must cover rising equipment and bandwidth expenses because of its rapid growth, despite going years without attempting to generate revenue.
